英文摘要
      For a discrete fuzzy system, stability of discrete switched fuzzy systems is presented in this paper. Using the switching technique, single Lyapunov function and multiple Lyapunov functions method, the continuous state feedback controller is designed to ensure that the relevant closed-loop system is asymptotically stable. Moreover, switching strategy achieving global asymptotic stability of the discrete switched fuzzy system is given. In this model, each subsystem of switched system is a discrete fuzzy system, and a common parallel distributed compensation controller is presented. The main condition is also given in form of convex combinations and matrix inequalities which are more solvable. Finally, a simulation shows the feasibility and the effectiveness of the method.
