Controlling strategy research on active front steering system

摘要

The structure and principle of the active front steering system (AFS) are introduced and the dynamic model of AFS is established in this paper. In order to improve the AFS steering characteristic, the PID controller and Fuzzy-PID controller are discussed. The simulation results show that rising time of the new control strategy is reduced a lot compared with traditional PID algorithm. The system performance is optimized and the fast tracking of AFS system is realized.
