Paper Abstract

The object of this research was to compare the performances of the active suspension system with three different control strategies. At first, a two degree-of-freedom vehicle model was established in order to study the basis feature of the active suspension system. Then three different control strategies including fuzzy control, optimal control and fuzzy-PID control were designed for the model. Each control strategy has its own characteristics. Therefore, their advantages and disadvantages were discussed in details. The simulation results show that the performances of the active suspension with three different control strategies are improved in riding comfort obviously and the fuzzy-PID control takes the advantages of both fuzzy control and PID control. It can be concluded that the fuzzy-PID control is a useful strategy for the active suspension system.
