摘　　要：对轮毂永磁电机矢量控制系统展开了研究。电机控制系统采用霍尔位置传感器跟踪永磁电机磁链,经矢量坐标变换后应用SPWM技术对电流进行控制。针对传统SPWM技术直流电压利用率低的缺点,采用了一种注入3次谐波为三角波的SPWM控制技术,以提高直流电压的利用率,从而提高电机的输出效率;采用该方法,也容易实现控制算法的设计。This paper studies about an in-wheel permanent magnet motor（PM） vector control system.Motor control system uses hall position sensors to track the flux of PM aplies the SPWM control technology to control current after the vector coordinates changes.For the shortcoming of low-utilization of DC voltage in the traditional SPWM control technology,the SPWM control technology is used in which a third harmonic of triangle wave is injected to improve the utilization of DC voltage,so that output efficiency of the motor can be much higher.Also,this methods can easily realize the design of control Algorithms.
