Abstract :
In this paper, using the permanent magnet synchronous motor (PMSM) as the motor of electric power steering system; establish mathematical models of the system, the completion of the EPS system architecture design. Adopt the composite method of Feedforward and the fuzzy PI control track on the target current, it´s improve the speed and accuracy response of system, reducing the tracking delay. Combine with steering system model, two freedom degrees vehicle model designing the power curve of control algorithm and simulating the overall system. The results of simulation show that the design of the curved power algorithm achieves to a good target of power control, and the system is stability.
