Abstract:A quarter-automobile active suspension model was proposed. High speed on/off solenoid valves were used as control valves and fuzzy control was chosen as control method . Based on force analyses of system parts, a mathematical model of the active suspension system was established and simplified by linearization method. Simulation study was con-ducted with Matlab and three scale coefficients of fuzzy controller (ke,kec,ku) were acquired. And an experimental device was designed and produced. The results indicate that the active suspension system can achieve better vibration isola-tion performance than passive suspension system, the displacement amplitude of automobile body can be reduced to 55%.Fuzzy control is an effective control method for active suspension system.

 

Key words: active suspension system; fuzzy control; high speed on/off solenoid valve; simulation
