H∞ control for uncertain discrete fuzzy system with both state and input delays
In this paper, a new approach to Hinfin controller design for a class of uncertain discrete T-S fuzzy systems are proposed. According to the Lyapunov stability theory as well as parallel distributed compensation (PDC), several sufficient conditions for stabilization of considered systems are derived. The design procedure based on LMI for the fuzzy robust controller is given, which guarantee the closed-loop system is asymptotically stable and the effect of disturbance input on the controlled output is reduced to a prescribed level. The simulation results show the proposed method is effective.
