Combined fuzzy-PID control for air suspension of car

One quarter air suspension model and the white-noise road model are established by taking the air suspension system of car as a study case in it,the dynamic integration between the fuzzy control theory and PID control strategy is applied to active control of the air suspension system.At the same time simulation study is carried out by utilizing MATLAB/Simulink,which results shows that,compared with the traditional PID and the fuzzy control,the control of the semi-active air suspension may reduce the sprung mass acceleration and suspension action itinerary with better robustness advantages under the combined fuzzy PID control strategy,and the ride comfort of the car is improved to a certain degree.
