| Abstract: | Through analyzing and physical model simplifying,this paper built a dynamic model for the electric power steering system(EPS).In order to reduce the steering torque and improve the return ability performance,a return ability controlled algorithm for the electric power steering system is developed and a controlling strategy,based on the estimation of steering wheel angle,is also discussed.Meanwhile,simulations and comparisons are conducted for the controlling strategy.The results show that the proposed controlling strategy can improve the return ability and stability of the steering wheel. |
