摘　　要：在深入分析永磁同步电机(PMSM)数学模型的基础上,结合电动助力转向(EPS)系统的结构与助力电机的助力特性,以永磁同步电机为助力电机,提出采用电流滞环跟踪控制策略.借助Matlab/Simulink软件平台,分别建立助力永磁同步电机及电流滞环跟踪控制系统仿真模型,以此为对象研究当某A0级轿车处于低速、中速和高速时在该控制策略下助力电机输出扭矩的可行性及采用该控制策略的响应速度与抗干扰能力.通过其仿真结果验证了该控制策略的可行性、有效性.In depth analysis of Permanent Magnet Synchronous Motor （PMSM） based on the mathematical model , and charac- teristics and structure of the assist motor for Electric Power Steering（EPS） system, hysteresis current tracking control strategy has been proposed and adopted. The paper established the simulation models of Permanent Magnet Synchronous Motor and hysteresis current tracking control system based on Matlab/Simulink to research on the torque ,response speed and anti-jamming capability for A0 class car at low , medium and high speed. The results verified the control strategy.
