Simulation of Automobile Hydraulic Semi-active Suspension with Fuzzy Controlling System on Simulink

The two-degree of freedom semi-active hydraulic suspension model for a quarter of vehicle is built up, then the designing way of automobile hydraulic semi-active suspension with fuzzy controller is introduced in fuzzy system. The comparison study through simulation by using MATLAB/Simulink shows that the performance of hydraulic semi-active suspension with fuzzy controller is better than that of passive suspension. It is a successful example of semi-active suspension in vehicle design application.
