Abstract :
This paper presents fault-tolerant control (FTC) architecture for vehicle lateral dynamics described by Takagi-Sugeno (TS) fuzzy model with parametric uncertainties and sensor faults. Using the LMI formulation, the T-S uncertain fuzzy model of vehicle dynamics is used to design an output feedback observer-based controller, a method based on observer bank is then investigated for detection, isolation and accommodation of sensor faults. Simulations show that the sensor faults are detected immediately after their occurrences and illustrate the proposed FTC strategy.
