摘      要：The problems of relaxed stability conditions and state feedback Hcontroller designs are studied for continuous-time T-S fuzzy systems using fuzzy Lyapunov functions approach.A new stability conditions are obtained by relaxing the stability conditions derived in previous papers,and a sufficient LMI conditions which guarantee the existence of the state feedback Hcontroller for T-S fuzzy systems is *** the solving approach for BLMI is studied based on convex optimization *** the effectiveness of the proposed approach is shown through two numerical examples.
