Abstract：In order to solve the problem of vertical vibration aggravation of electric vehicle driven by in-wheel motor, a variable domain fuzzy control strategy based on T-S fuzzy is designed for active suspension, and the design method of contraction-expansion factors is modified to improve the control accuracy and self-adaptability of the controller under multiple working conditions. Based on the quarter-car model, the dynamic analysis is carried under random road and joint road excitations. The proposed T-S variable domain fuzzy control is compared with single T-S fuzzy control and Mamdani variable domain fuzzy control, the effect of this new controller is verified by hardware in the loop experiment. The results show that the T-S variable domain fuzzy control can effectively improve vehicle ride comfort, and has better multi-condition adaptability than single T-S fuzzy control, and Mamdani variable domain fuzzy control.
