Abstract
This study presents the vibration of an adaptive sliding mode fault-tolerant control for MR suspension system considering the partial fault of MR dampers. After formulating a full car dynamic model featuring four MR dampers, the fault model of the MR dampers due to the varying working temperature is derived. An adaptive sliding model fault-tolerant control strategy is then proposed after the occurrence of a fault. The performance of the proposed control scheme is evaluated and compared under the bump road condition and presented in time domain. The results show that significant gains are made in the presence of the partial fault of an MR damper. The control scheme could reduce the effect of the partial fault of the MR damper on system performance.
