Switching Controller Design for Stochastic Switched Fuzzy Systems

This paper addresses the problem of designing switching control for a class of stochastic switched fuzzy systems with time-delay. Firstly, a stochastic switched fuzzy system can precisely describe continuous and discrete dynamics as well as their interactions in the complex real-world systems. Next, switching control algorithm and switching law design of the state-dependent form are developed such that the stability is guaranteed. Since convex combination techniques are used to derive the delay independent criteria, some subsystems are allowed to be unstable. Finally, various comparisons of the elaborated examples are conducted to demonstrate the effectiveness of the proposed control design approach. All results illustrate good control performances as desired.
