Fault reconstruction in the vehicle electronic stability control based on sliding mode observers
基于滑模观测器的车辆电子稳定性控制系统故障重构

For the global dynamic model of a vehicle based on fuzzy Takagi-Sugeno(T-S) system, we discuss an on-line fault detection and reconstruction scheme for the yaw rate and lateral acceleration sensor in a vehicle electronic stability control system. The observer is designed based on the sliding mode control theory, the L2 gain from the unknown input to the fault reconstruction error is guaranteed. Real data obtained from the vehicle verifies the effectiveness of the design technique.
