Abstract

This paper deals with the disturbance of nonlinear Takagi-Sugeno (T-S) fuzzy system. Based on piecewise fuzzy Lyapunov function and LMI method, the systematic design procedures were given and the sufficient conditions for closed-loop system stability were derived and the parameters design method of gamma-superior H_infin controller for closed-loop system was provided. Simulation results show the effectiveness of the proposed method.
