Abstract :
Stability, rapidity and accuracy are very important performances in Electric Power Steering (EPS). In this paper, it was explained that the contradictions among these performances can´t be avoided when using traditional feedback control methods. To resolve this problem, the EPS model and feed-forward control method were studied. And then, a fuzzy PID associate with feed-forward control algorithm was proposed. Through the real vehicle experimental verification, the integrated control algorithm can improve the performance of EPS significantly.
