Fuzzy control and simulation on air suspension system

Zhao Hua-wei

Abstract

A multi-input multi-output fuzzy controller was designed based on the quarter-car dynamic model,To integrated control the air-spring stiffness and the shock absorber damper,The dynamic simulation model of the fuzzy control suspension was built up by MATLAB/SIMULINK.The simulation results show that compared with the positive air suspension,the fuzzy controlled air suspension could be used to reduce the sprung mass acceleration with better robustness,and improve ride comfort.The study has provided the academic reference to the integrated control of air suspension.
