Based on LMI approach and Lyapunov theory, non-fragile guaranteed cost control for a class of delta-operator uncertain time-delay systems is studied. A sufficient condition for the existence of non--fragile state feedback guaranteed cost controller is presented, and the design method of such controller is proposed. Based on that mentioned, the design problem of the optimal guaranteed cost controller is given by solving a corresponding convex optimization problem. Finally, a numerical example is given to illustrate the feasibility and advantage of the design method.
