T–S FUZZY CONTROL FOR ACTIVE SUSPENSION OF DISTRIBUTED DRIVE ELECTRIC VEHICLE

In order to solve the problem of vertical vibration aggravation of electric vehicle driven by in-wheel motor, a T–S fuzzy control strategy is designed for active suspension based on the quarter-car model. Dynamic analysis is carried under B-class random road and variable road excitations, considering the adaptability of the controller when vehicle parameters are uncertain, and the control effect of T–S fuzzy controller is studied when vehicle parameters are changing. The proposed T–S fuzzy control is compared with PID control and passive suspension, and the effect of this controller is verified by hardware in the loop experiment. The results show that the proposed T–S fuzzy control strategy can effectively improve vehicle ride comfort and has better multi-condition adaptability than PID control.
