Fuzzy switched modeling and control for a class of hybrid system

Abstract

Fuzzy switched modeling algorithm of hybrid system is proposed, parallel distributed compensation method is used to design fuzzy switched controller based on local reference model. The Lyapunov stability conditions of closed-loop system are proven. With the existence of unique symmetric positive definite matrix P, the stability of global fuzzy switched system can be guaranteed. The stable switching sequence can be derived from Corollary. The comparison simulations with sliding mode variable structure indicate that the proposed algorithm has better global performance and smooth switching characteristic.
