  • On a connectivity matrix formula for tensegrity prism plates

    K. Nagase, T. Yamashita, N. Kawabata (Part: Corresponding author )

    Mechanics Research Communications ( Elsevier Ltd )  77   29 - 43   2016.10  [Refereed]

     View Summary

    This paper considers tensegrity structures constructed from repetition of simple fundamental units. The tensegrity prism is chosen as a fundamental unit, which allows us to build plates, columns, towers, and their variations. The connectivity matrix plays a central role in analysis and design of tensegrity structures. This paper provides a systematic way to construct connectivity matrices for tensegrity structures constructed from repetition of tensegrity prisms. The number of units and node locations (shape) can be chosen arbitrarily. As an application of the connectivity matrix, a minimal-mass design subjected to force equilibrium (force balance) and yield and buckling stress constraints is shown.

  • Wave analysis and control of double cascade-connected damped mass-spring systems

    K. Nagase (Part: Lead author )

    MECHANICS RESEARCH COMMUNICATIONS ( PERGAMON-ELSEVIER SCIENCE LTD )  70   49 - 57   2015.12  [Refereed]

     View Summary

    This paper presents wave analysis and control for double cascade-connected damped mass-spring systems, whose mass is connected beyond the adjacent masses. The system is motivated by a cantilevered tensegrity beam supporting tensile and compressive forces. The wave solution is derived from a recurrent formula, and the properties of the propagation constants are precisely investigated. Elimination of reflected waves provides the impedance matching controller. We show that the impedance matching controller can be constructed from a similarity transformation of the characteristic impedance matrix by a matrix composed of the propagation constants. A numerical example of vibration control of a tensegrity beam is shown. (C) 2015 Elsevier Ltd. All rights reserved.

  • 自己釣り合い状態を利用したマルチエージェントシステムのフォーメーション制御

    MASUDA Yoichi, NAGASE Kenji (Part: Corresponding author )

    計測自動制御学会論文集 ( The Society of Instrument and Control Engineers )  51 ( 10 ) 744 - 754   2015.10  [Refereed]

     View Summary

    This paper proposes a cooperative formation control of multi-agent systems by using self-equilibrium condition based on the force-density method. The force-density method is widely used in structural mechanics, which enables us to design the equilibrium of axially loaded structures (tensegrity structures) with non-zero control force. The control law is derived from a potential function of linear springs connecting the agents. Replacing the design variables in linear springs by force density (control force per unit length) and member constant (product of spring constant and rest length), the design problems can be described as convex optimization problems. As an application of the proposed strategy, a control design method for multi-agent systems with communication time-delays is provided. Permissible time-delay is maximized by minimizing the maximum eigen value of the tangent rigidity matrix. Numerical examples show that the permissible time-delay is increased by introducing the non-zero internal force.

  • Double-Helix Tensegrity Structures

    K. Nagase, R. E. Skelton

    AIAA JOURNAL ( AMER INST AERONAUTICS ASTRONAUTICS )  53 ( 4 ) 847 - 862   2015.04  [Refereed]

     View Summary

    This paper describes a class of tensegrity systems that are formed from a common type of connectivity, having a double-helix configuration. Structures made from such internal patterns will be called a double-helix tensegrity. This paper derives the connectivity matrix for the double-helix tensegrity class of structures. This generalized common mathematical formulation will allow efficient computations for a large class of tensegrity systems, which can have many different configurations, albeit employing the same rules for connecting components. Special cases of these configurations include torus, cylinders, paraboloids, spheres, ellipsoids, and other configurations.

    K. Nagase, R. E. Skelton

    Mechanics Research Communications ( Elsevier Ltd )  59   14 - 25   2014  [Refereed]

     View Summary

    We write the equations of motion in vector form for any class k tensegrity system dynamics. The network approach yields a connectivity matrix and nodal matrix, providing the dynamics of any network of bars, pipes and cables. The class 1 (bars do not connect) dynamics are described together with a constraint added to allow bar to bar connections. Damping and gravity forces as well as base movement can be handled in a unified framework. The constraint force is eliminated to yield a compact set of vector equations. © 2014 Elsevier Ltd.

     View Summary

    Switching shunt damping technique is one of the most effective methods for structural vibration control due to its simplicity and robustness. However, because of the spillover, conventional switching LR shunt damping technique has limitation of its application to multi degree-of-freedom systems. In this paper, we propose a new switching shunt damping technique to reduce vibration of a specified mode of multi degree-of-freedom systems. Basic idea of the proposed method is to recover the loss of electrical charge of the piezoelectric element by charge supply from parallel connected capacitors. Effectiveness of the proposed method is examined numerically and experimentally.

     View Summary

    This paper investigates wave-based analysis and impedance matching for the ladder electric networks. The results are a generalized version of our previous work for the cascade connected damped mass-spring systems. We first clarify the class of the ladder networks which satisfies the three conditions for the propagation constants to be analyzed by the wave-based analysis. Secondly, for the class of the networks, we investigate the analyticity of the secondary constants and positive real property of the characteristic impedances. Properties of the impedance matching are also investigated. A numerical example for a mechanical system shows effectiveness of the impedance matching for vibration control.

    This paper considers the fault diagnosis for vibrating systems. An estimation method of the mode shapes by using independent component analysis is presented. The harmonic signal, impulse signal, and white noise are available for the input signals. The method only requires independence of the modal coordinates, and it does not require the physical parameters of vibrating systems and the inputs' information. In the numerical example, fault diagnosis for a plate is presented as an application of the proposed method.

    This paper considers a method to identify the parameters for the piezoelectric shunt damping. Employing the self-sensing actuator methodology, the proposed method uses the piezoelectric element for shunt damping as a sensor/actuator, and only a simple circuit is required for the experimental setup. From the frequency response obtained from the voltage signals of the circuit, the parameters are calculated simply by the linear least squares method.

     View Summary

    Passive piezoelectric shunt damping is a vibration suppression method using a piezoelectric element which is electrically shunted by a passive electrical circuit. This paper shows a method of optimizing the values of the elements of the shunt circuits based on the robust performance index against the model uncertainties. For the optimization, the worst-case peak gain of the transfer function is selected as a cost function. From the results of the optimization for the LR shunt circuit, we investigate some required properties for the robustness of shunt circuits. As an example of the robust shunt circuits, the optimization for the LR-LRC shunt circuit is also presented. The experimental results demonstrate the efficiency of the proposed method.

    2015 15TH INTERNATIONAL CONFERENCE ON CONTROL, AUTOMATION AND SYSTEMS (ICCAS) ( IEEE )    597 - 602   2015  [Refereed]

     View Summary

    This paper proposes a method for designing a control law for a distributed cooperative formation control of multi-agent systems that positively utilizes self-equilibrium conditions on the basis of the force density method. The force density method is widely used in structural mechanics, and enables us to design the equilibrium of axially loaded structures (tensegrity structures) with a non-zero internal force. The control law is derived from a potential function of virtual linear springs connecting the agents. Replacing the design variables in linear springs by force density (control force per unit length) and member constant (product of spring constant and rest length), the design problems can be described as convex optimization problems. Considering the trade-off between the stiffness of target formation and the control effort, we choose a design objective to minimize the maximum eigenvalue of the tangent stiffness matrix under a constraint of stability. Numerical examples show that the proposed method suppresses the maximum eigenvalue of the tangent stiffness matrix, and decreases the control effort by introducing the non-zero internal force.

     View Summary

    This paper provides a unified framework for minimal mass design of tensegrity systems. For any given configuration and any given set of external forces, we design force density (member force divided by length) and cross-section area to minimize the structural mass subject to an equilibrium condition and a maximum stress constraint. The answer is provided by a linear program. Stability is assured by a positive definite stiffness matrix. This condition is described by a linear matrix inequality. Numerical examples are shown to illustrate the proposed method. © 2014 SPIE.

    IFAC Proceedings Volumes (IFAC-PapersOnline) ( International Federation of Automatic Control )  18 ( 1 ) 11562 - 11567   2011  [Refereed]

     View Summary

    This paper is concerned with a new feedback control design methodology for vibration control of flexible structures by the wave control. In the wave control, controllers are usually designed to minimize the reflection coefficient based on the wave analysis. However, because the method utilizes the wave analysis directly, it has been mainly applied to simple uniform structures, and control design method with some other control objectives has not been established yet. In this paper, aiming to establish a control design method for more complex systems and more complex control design, we propose a method based on the impedance matching index, which represents the difference of the transfer functions between the closed system and the controller. The index is motivated by the wave analysis and control for the uniformly varying ladder networks, an electric circuit analogy of a class of mechanical systems. As a design example for vibration control of mechanical systems, optimal tuning of the passive damper and the dynamic absorber by the index is conducted in the numerical example. © 2011 IFAC.

    In this paper, we discuss control of contact coordinates for a contact point between a sphere and a plane with pure rolling contact by using iterative closed paths on the sphere with contstrained rolling motion. We first analyze the boundary of the reachable area by the closed path with constrained rolling motion. Utilizing the result, we second propose a method which converge all the contact coordinates to a target point by the iteration of a finite number of the closed paths. A numerical example where the rolling motion is restricted to the area on the semisphere shows the effectiveness of the proposed method. ©2005 IEEE.

    Piezoelectric shunt damping is a method to reduce structural vibration by shunting a piezoelectric element with an electrical circuit. This paper proposes a method to identify the physical parameters that are required to design piezoelectric shunt damping systems. Employing self-sensing actuator methodology, the proposed method requires no additional sensor or actuator other than a simple bridge circuit. The parameters can be identified from a transfer function simply by linear least squares method. To demonstrate the validity of the proposed method, the shunt damping of the steel plate with the piezoelectric ceramic is performed based on the identified parameters.

    This papaer considers the fault diagnosis for vibrating systems. An estimation method of the mode shapes by using independent component analysis is presented. The harmonic signal, impulse signal, and white noise are available for the input signals. The method only requires independence of the modal coordinates, and it does not require physical parameters of vibrating systems and inputs' information. In the numerical example, fault diagnosis for a plate is presented as an application of the proposed method.

  • 614 Passive piezoelectric shunt damping based on minimizing the robust performance index

    TAKAGI Kentaro, NAGASE Kenji, OSHIMA Kazuhiko, HAYAKAWA Yoshikazu, ICHIKAWA Hiroyuki

    The Proceedings of the Dynamics & Design Conference ( The Japan Society of Mechanical Engineers )  2003 ( 0 ) _614 - 1_-_614-6_   2003

     View Summary

    Passive piezoelectric shunt damping is a vibration suppression method using a piezoelectric element which is electrically shunted by a passive electrical circuit. This paper shows a method of optimizing the values of the elements of the shunt circuits based on the robust performance index against the model uncertainties. For the optimization, the worst-case peak gain of the transfer function is selected as a cost function. From the results of the optimization for the LR shunt circuit, we investigate some required properties for the robustness of shunt circuits. As an example of the robust shunt circuits, the optimization for the LR-LRC shunt circuit is also presented. The experimental results demonstrate the efficiency of the proposed method.

     View Summary

    A method to measure the modal coordinates of a simply supported rectangular plate using an equally segmented piezoelectric film is studied. Modal sensors which can measure specific modal coordinates by shaping distributed piezoelectric sensors were proposed by Lee et al. However, basically, it can be only applied to one dimensional vibrations and only measure the specific modal coordinates corresponding to the shape of the sensor. In this paper, we propose a method, in which estimated modal coordinates are obtained by the sum of appropriately weighted sensor signals from the segmented piezoelectric film. This method can be easily applied to two dimensional vibrations and can measure arbitrary modal coordinates by selecting the weight. In this paper, the weight is determined to minimize a cost function. The orthogonality of the unit modal sensing signal vectors for a simply supported rectangular plate with an equally segmented piezoelectric film is proven, and the transpose of the unit model sensing signal matrix is chosen as the weight. Effects of aliasing caused by finite segmentation are also discussed. Simulation is shown to prove efficiency.

  • Active Vibration Control of a Multi-Story Structure by Impedance Matching

    Nihon Kikai Gakkai Ronbunshu, C Hen/Transactions of the Japan Society of Mechanical Engineers, Part C   67 ( 658 ) 1814 - 1819   2001

     View Summary

    This study considers active vibration control of a multi-story structure which consists of bar-connected masses repeated in the vertical direction with active mass drivers installed on the toP. As an alternative to the vibration mode approach, the traveling wave approach is applied. To implement the impedance matching controller which is proposed for a damped mass-spring system, the loop shaping design procedure is used to consider the dynamics of the actuator and the sensor noise. The designed controller has similar properties of the impedance matching controller, that is, it is efficient for the disturbance at any position and the towers with any stories. Experimental results are shown to evaluate efficiency. © 2001, The Japan Society of Mechanical Engineers. All rights reserved.

     View Summary

    This paper proposes a method for designing a control law for a distributed cooperative formation control of multi-agent systems that positively utilizes self-equilibrium conditions on the basis of the force density method. The force density method is widely used in structural mechanics, and enables us to design the equilibrium of axially loaded structures (tensegrity structures) with a non-zero internal force. The control law is derived from a potential function of virtual linear springs connecting the agents. Replacing the design variables in linear springs by force density (control force per unit length) and member constant (product of spring constant and rest length), the design problems can be described as convex optimization problems. Considering the trade-off between the stiffness of target formation and the control effort, we choose a design objective to minimize the maximum eigenvalue of the tangent stiffness matrix under a constraint of stability. Numerical examples show that the proposed method suppresses the maximum eigenvalue of the tangent stiffness matrix, and decreases the control effort by introducing the non-zero internal force.

     View Summary

    This paper provides a unified framework for minimal mass design of tensegrity systems. For any given configuration and any given set of external forces, we design force density (member force divided by length) and cross-section area to minimize the structural mass subject to an equilibrium condition and a maximum stress constraint. The answer is provided by a linear program. Stability is assured by a positive definite stiffness matrix. This condition is described by a linear matrix inequality. Numerical examples are shown to illustrate the proposed method. © 2014 SPIE.

  • Vibration control of flexible structures based on impedance matching index

    Kenji Nagase, Yasuyuki Takeuchi

    IFAC Proceedings Volumes (IFAC-PapersOnline)  2011   International Federation of Automatic Control

     View Summary

    This paper is concerned with a new feedback control design methodology for vibration control of flexible structures by the wave control. In the wave control, controllers are usually designed to minimize the reflection coefficient based on the wave analysis. However, because the method utilizes the wave analysis directly, it has been mainly applied to simple uniform structures, and control design method with some other control objectives has not been established yet. In this paper, aiming to establish a control design method for more complex systems and more complex control design, we propose a method based on the impedance matching index, which represents the difference of the transfer functions between the closed system and the controller. The index is motivated by the wave analysis and control for the uniformly varying ladder networks, an electric circuit analogy of a class of mechanical systems. As a design example for vibration control of mechanical systems, optimal tuning of the passive damper and the dynamic absorber by the index is conducted in the numerical example. © 2011 IFAC.

    In this study, simulations and experiments were done with experimental one-legged robot, and jump motion results with or without impedance matching design were compared. Jumping motion of the experimental robot was captured by high-speed video camera, and jumping height was measured from captured movie. As the results, jumping motion with impedance matching design was about one and a half times higher than that without impedance matching design in both experiments and simulations.

     View Summary

    This paper investigates the wave-based analysis and the wave control for ladder electric networks. The results are a generalized version of our previous work for the cascade connected damped mass-spring systems. We first clarify the class of the ladder networks which satisfies the three condition for the propagation constants to be analyzed by the wave-based analysis. Secondly, for the class of the networks, we investigate the analyticity of the secondary constants and positive real property of the characteristic impedances. Properties of the impedance matching are also investigated. A numerical example for a mechanical system shows effectiveness of the impedance matching for vibration control. © 2005 IEEE.

     View Summary

    In this paper, we discuss control of contact coordinates for a contact point between a sphere and a plane with pure rolling contact by using iterative closed paths on the sphere with contstrained rolling motion. We first analyze the boundary of the reachable area by the closed path with constrained rolling motion. Utilizing the result, we second propose a method which converge all the contact coordinates to a target point by the iteration of a finite number of the closed paths. A numerical example where the rolling motion is restricted to the area on the semisphere shows the effectiveness of the proposed method. ©2005 IEEE.

  • Parameter identification method for piezoelectric shunt damping

    Kentaro Takagi, Kenji Nagase, Kazuhiko Oshima, Yoshikazu Hayakawa, Zhi-Wei Luo

    Proceedings of SPIE - The International Society for Optical Engineering  2005   SPIE

     View Summary

    Piezoelectric shunt damping is a method to reduce structural vibration by shunting a piezoelectric element with an electrical circuit. This paper proposes a method to identify the physical parameters that are required to design piezoelectric shunt damping systems. Employing self-sensing actuator methodology, the proposed method requires no additional sensor or actuator other than a simple bridge circuit. The parameters can be identified from a transfer function simply by linear least squares method. To demonstrate the validity of the proposed method, the shunt damping of the steel plate with the piezoelectric ceramic is performed based on the identified parameters.

    The Proceedings of the Dynamics & Design Conference  2003   The Japan Society of Mechanical Engineers

     View Summary

    Passive piezoelectric shunt damping is a vibration suppression method using a piezoelectric element which is electrically shunted by a passive electrical circuit. This paper shows a method of optimizing the values of the elements of the shunt circuits based on the robust performance index against the model uncertainties. For the optimization, the worst-case peak gain of the transfer function is selected as a cost function. From the results of the optimization for the LR shunt circuit, we investigate some required properties for the robustness of shunt circuits. As an example of the robust shunt circuits, the optimization for the LR-LRC shunt circuit is also presented. The experimental results demonstrate the efficiency of the proposed method.

  • An Estimation Method of Mode Shapes by Independent Component Analysis and Its Application to Fault Diagnosis

    TAKAGI Kentaro, NAGASE Kenji, HAYAKAWA Yoshikazu, KAWASAKI Tokuo

    The Proceedings of the Symposium on the Motion and Vibration Control  2003   The Japan Society of Mechanical Engineers

     View Summary

    This papaer considers the fault diagnosis for vibrating systems. An estimation method of the mode shapes by using independent component analysis is presented. The harmonic signal, impulse signal, and white noise are available for the input signals. The method only requires independence of the modal coordinates, and it does not require physical parameters of vibrating systems and inputs' information. In the numerical example, fault diagnosis for a plate is presented as an application of the proposed method.

    Kenji Nagase, Yoshikazu Hayakawa

    Nihon Kikai Gakkai Ronbunshu, C Hen/Transactions of the Japan Society of Mechanical Engineers, Part C  2001  

     View Summary

    This study considers active vibration control of a multi-story structure which consists of bar-connected masses repeated in the vertical direction with active mass drivers installed on the toP. As an alternative to the vibration mode approach, the traveling wave approach is applied. To implement the impedance matching controller which is proposed for a damped mass-spring system, the loop shaping design procedure is used to consider the dynamics of the actuator and the sensor noise. The designed controller has similar properties of the impedance matching controller, that is, it is efficient for the disturbance at any position and the towers with any stories. Experimental results are shown to evaluate efficiency. © 2001, The Japan Society of Mechanical Engineers. All rights reserved.

  • Modal filtering for simply supported plate using equally segmented piezoelectric film

    K Takagi, K Nagase, K Oshima, Y Hayakawa

    PROCEEDINGS OF THE 2001 AMERICAN CONTROL CONFERENCE, VOLS 1-6  2001   IEEE

     View Summary

    A method to measure the modal coordinates of a simply supported rectangular plate using an equally segmented piezoelectric film is studied. Modal sensors which can measure specific modal coordinates by shaping distributed piezoelectric sensors were proposed by Lee et al. However, basically, it can be only applied to one dimensional vibrations and only measure the specific modal coordinates corresponding to the shape of the sensor. In this paper, we propose a method, in which estimated modal coordinates are obtained by the sum of appropriately weighted sensor signals from the segmented piezoelectric film. This method can be easily applied to two dimensional vibrations and can measure arbitrary modal coordinates by selecting the weight. In this paper, the weight is determined to minimize a cost function. The orthogonality of the unit modal sensing signal vectors for a simply supported rectangular plate with an equally segmented piezoelectric film is proven, and the transpose of the unit model sensing signal matrix is chosen as the weight. Effects of aliasing caused by finite segmentation are also discussed. Simulation is shown to prove efficiency.
