Finite-time H-infinity synchronization of semi-Markov jump Lur'e systems

Abstract

This paper investigates the problem of finite-time H-infinity synchronization for semi-Markov jump Lur'e systems with time-varying delay and external disturbance. The purpose of this work is to design a mode-dependent state-feedback controller to ensure that the synchronization-error system achieves finite-time synchronization with a prescribed H-infinity performance index. A criterion for the finite-time synchronization is proposed by using appropriate Lyapunov functional and two recently developed inequalities. Then, a design method for the required state-feedback controller is presented with the application of several decoupling techniques. Finally, an example is provided to illustrate the applicability of the proposed control method.
