Fuzzy Sliding Mode Control of Semi-active Suspension Based on Half-car Decoupling
摘要
Abstract
To improve car comfort, a fuzzy sliding mode control for semi-active seat suspension based on half-car decoupling model is proposed. First of all, the half-car dynamic model of the passive suspension system is established and analyzed. Then, it is converted equivalently into two sets of typical dynamic equations. Therefore, decoupling of the half-car suspension system into a quarter-car suspension system is realized. A fuzzy sliding mode controller (FSMC) for the semi-active seat suspension based on the decoupled quarter car is proposed. In the FSMC, an ideal skyhook model is taken as the reference model, and the dynamic errors between the seat suspension and reference model are introduced to the sliding mode. Further the fuzzy strategy is used suppress the chattering occurred in the above sliding mode control by fuzzifying the switch function and its derivative. by comparing the output force of the magnetorheological (MR) damper with the desired force solved by the fuzzy sliding mode controller, the voltage to control the MR damper is calculated. The comparison results of FSMC with PID,sliding mode control by numerical simulations show that the vibration reduction effect of the semi-active seat is obviously improved. The proposed method provides a reference for the control of the semi-active seats.关键词
