Abstract

Abstract:

The problem of stability for a class of T-S fuzzy time-delay systems was investigated . By using controller switching technique and multiple Lyapunov function method, in several proposed PDC controllers, an appropriate switching law was designed to ensure that the closed-loop system is asymptotically stable for all admissible uncertainties. A simulation result demonstrates the feasibility and the effectiveness of the designed method.
