    Abstract:

    In order to solve the current tracking control problem in electric power steering (EPS), the system mathematical model was established and the system type was analyzed, disadvantages of the conventional PID control and fuzzy PID control were studied. Using the feed-forward and feedback integrating control theory, a feed-forward control integrated with fuzzy PID feedback control algorithm was proposed. Experiment comparisons showed that the proposed algorithm could significantly improve the system stability, response rapidity and following accuracy in current control of electric power steering system. 
