Abstract: The nonlinear systems is construced by a class of T-S fuzzy systems with state uncertainty and time-delay uncertainty. Firstly,the fuzzy state feedback controller is designed,the control gain matrix of the controller is gived with the linear matrix inequality(LMI)technique;Next ,quadratic stability is found by the Lyapunov stability theory;Finally,the numerical example shows that the method is effective.

Key words: T-S model, quadratic stability, linear matrix inequality(LMI), time-delay system
