Simulation Analysis for Electric Power Steering Control System Based On Permanent Magnetism Synchronization Motor

摘要：

　　In this paper the math model of Electric Power Steering system (EPS) based on Permanent Magnetism Synchronization Motor (PMSM) is built in MATLAB,which includes the simulation model of the steering mechanical system,PMSM and ECU of EPS.With the control strategy of direct-axis current on zero,SVPWM is used to drive PMSM.Based on the linear pattern assistant characteristic,this simulation model has emulated the systems performance on the condition of sine input of the steering wheel torque and achieves good real time control effect of assistant current and assistant torque output of PMSM.
