具有半马尔可夫跳跃的时变时滞系统的滑模控制研究

Abstract

Abstract:

This paper studies the sliding mode controller design problem for uncertain continuous time-varying delay systems with the semi-Markov jump. Firstly, by studying the dynamic characteristics of the system, combined with the sliding mode surface, a singular system is established to describe the holonomic dynamics of the sliding mode. Then, building an appropriate Lyapunov functional by taking into account more information about time delay, a sufficient condition that guarantees the existence of sliding mode surface and the stochastic stability of sliding mode dynamics is given. Based on this, a sliding mode controller is designed to make the closed-loop system finally converge to the sliding mode surface. Finally, a numerical example is given to show the effectiveness of the developed approach.
