Simulation of Hydraulic Semi-active Suspension System Based on the Adaptive Fuzzy Control
A four-degree of freedom semi-active hydraulic suspension model and the equation of state for a half of vehicle are built. For time-variation and nonlinearity of the vehicles suspension system, it is appropriate to use the fuzzy control method that does not need to grasp the controlled object for the precise mathematical model. The double adaptive fuzzy controller is adopted to realize the control of the semi-active suspension of the vehicles when the input of controller is velocity of center of mass, pitch angular velocity and deviation variation respectively, the simulation results show that the control effect about the semiactive suspension of hydraulic pressure with the adaptive fuzzy controller is obviously better than the passive suspension, which can improve the ride comfort effectively.
