چکیده:

The main role of a car suspension system is to improve the ride comfort and to better the handling property. It usually consists of a spring and a damper. To improve the properties of suspension systems, many studies based on adaptive control methods, preview control, sliding mode control, ∞ H  control etc. have been done. In this paper, fuzzy logic is used to control active hydro pneumatic suspension. It is one of the most
active research and development areas of artificial intelligence at the present time, particularly in the automobile industry because fuzzy logic can improve vehicle ride comfort and road handling performance. The ride comfort is improved by means of the reduction of the body acceleration caused by the car body when road disturbances from uneven road surfaces, pavement points etc. act on the tires of running cars.
