【 摘 要 】
This paper deals with actuator faults detection and isolation for an actuated seat described by Takagi-Sugeno multiple models. The goal is to ensure the comfort and the security of the users in simulator applications. Sliding mode observers based on T-S models are designed to estimate the system state vector. Residuals are generated by the comparison of measured and estimated outputs. In this work, a multi-observers technique is used. It consists of the construction of many observers such that each observer must be robust to noises and to other uncertainties but sensitive to one actuator fault. Simultaneous faults occurring on the actuated seat can be detected and isolated using this method. Simulation results are given to show the effectiveness of this approach.
