摘要：
Because of the complex nonlinearity of electric power steering system, the actual current of motor can't follow the tracks of the target current well with PID controller. A compound controller of CMAC and PID is proposed for it. This controller realized the feedback control with traditional PID controller to make the electric power steering system stable, and realized the feed forward control with CMAC neural network controller to increase the response speed and control precision. Simulation results showed that actual current of motor can follow the tracks of the target current very well with the compound controller. Moreover, the compound control system of CMAC and PID is less sensitive to the change of parameters than that in PID control system.
