Abstract

H 驴 robust control and stability are addressed for a class of uncertain fuzzy systems with time-delays in both states and control inputs. Using a Lyapunov--Krasovskii functional in descriptor model transformation, we have presented the delay--dependent sufficient conditions of stability to ensure asymptotic stability of the system. To be less conservative in results, we employ an algorithm involving convex optimization in designing the state--feedback controller. The example shows the validity of our results.
