SIMULATION OF AUTOMOBILE HYDRAULIC SEMI-ACTIVE SUSPENSION WITH FUZZY CONTROLLING SYSTEM ON SIMULINK

A two-degree of freedom semi-active hydraulic suspension model for a quarter of vehicle is built and the automobile hydraulic semi-active suspension with fuzzy controller can be designed.The simulation by using MATLAB/Simulink shows that the performance of hydraulic semi-active suspension with fuzzy controller is better than that of a passive suspension.It is a successful application of semi-active suspension in vehicle design.
