Abstract :
This paper presents an approach useful to analyze the fault tolerant problem for the networked control systems(NCSs). A Takagi-Sugeno(T-S) fuzzy model with parametrical uncertainties is used to approximate the T-S model. We designed robust controllers both with the sensor failure and the actuator failure. The robust fault tolerances of the system were proved by Lyapunov function. This method avoid the difficulty of the solving the common matrix. Simulation results show the effectiveness of the proposed method.
