H-infinite Robust Tolerant Control for a Class of Nonlinear Systems with Uncertainties and Time Delays Based on Fuzzy Models
基于模糊模型的非线性不确定时滞系统的H-infinite鲁棒容错控制

The H-infinity robust tolerant control for nonlinear systems with uncertainties and time delays is studied. The Takagi-Sugeno(T-S) fuzzy model is employed to represent the nonlinear system. For the case of actuator fault and the existence of system disturbances, a sufficient condition for the existence of the H-infinity robust tolerant control law which guarantees robust stability of the system is given, based on the Lyapunov stability theory and the linear matrix inequality method. Simulation results show the effectiveness of the proposed approach.
