    Dynamic control of beams acted by multiple moving masses in resonance state using piezo-ceramic actuators

    , Article Proceedings of SPIE - The International Society for Optical Engineering ; 2012 ; 0277786X (ISSN) ; 9780819489982 (ISBN) Mofid, M ; Eftekhar Azam, S ; Afghani Khorasghan, R ; Sharif University of Technology

    Abstract
    In this article the constitutive equation of an Euler-Bernoulli beam, excited by multiple moving masses is considered. A set of multiple piezo-ceramic actuators is used to harness the dynamic response of the beam. In this regard the beam response is suppressed by utilizing a linear control algorithm with a time varying gain matrix and displacement-velocity feedback. The efficiency of the results is investigated through the numerical analysis of an example problem  

    Dual synchronization of chaotic systems via time-varying gain proportional feedback

    , Article Chaos, Solitons and Fractals ; Volume 38, Issue 5 , December , 2008 , Pages 1342-1348 ; 09600779 (ISSN) Salarieh, H ; Shahrokhi, M ; Sharif University of Technology

    Abstract
    In this paper the dual synchronization of chaotic systems via output feedback strategy is investigated. The slave chaotic systems are fed by a scalar signal generated by a linear combination of the master systems state variables. The sufficient condition and design procedure for dual synchronization are presented. The proposed method is applied for dual synchronization of the Lorenz-Rossler, Rossler-Chen and Duffing-Van der Pol chaotic systems through computer simulation. The results show the effectiveness and feasibility of the proposed algorithm. © 2008 Elsevier Ltd. All rights reserved  

    Multi-synchronization of chaos via linear output feedback strategy

    , Article Journal of Computational and Applied Mathematics ; Volume 223, Issue 2 , 15 January , 2009 , Pages 842-852 ; 03770427 (ISSN) Salarieh, H ; Shahrokhi, M ; Sharif University of Technology

    Abstract
    Multi-synchronization of chaotic systems based on the master-slave scheme as an extension of the dual synchronization problem is introduced. It is assumed that the only information available from the master systems is a linear combination of their state vectors. The design procedure for multi-synchronization through output feedback strategy is described and the sufficient condition is given. The performance of the proposed algorithm is numerically examined by applying it to the Chen-Lorenz-Rossler and the Duffing-Van der Pol chaotic systems. Simulation results show the effectiveness of the proposed scheme. © 2008 Elsevier B.V. All rights reserved
