摘要：
A fuzzy logic controller is proposed for the 1/4 vehicle semi-active suspension system with magneto-rheological damper. The vertical velocity and acceleration of the vehicle body are taken as the input of the fuzzy logic controller and the damper force is taken as the output of it. The fuzzy rules are deduced on basis of different kinds of membership functions and defuzzification methods. Then, Matlab Simulink is utilized to carry out simulation analysis on the whole system. The results show that the exactness carried out by the Gaussian membership function and by the utilization of area bisection method make the control effect satisfactory. Compared with the passive suspension, the semi active suspension has better performance with obviously reduced body vertical acceleration by using the fuzzy controller, which can greatly improve the vehicle ride comfort and handling stability.
