| Abstract: | This paper investigates the problems of non-fragile control for a class of uncertain discrete switched fuzzy control systems with time-delay.A sufficient condition for the existence of non-fragile state-feedback controllers and the switching law are proposed based on switching and multiple Lyapunov functions technique.The corresponding results are all formulated in terms of matrix inequalities.Finally,an illustrative example shows the feasibility and the effectiveness of the proposed approach. |
