摘　　要：传统方法在进行永磁同步电机驱动控制时,存在电机驱动转矩脉动大,频率不恒定的问题。为此,本文引入无传感器控制技术,对电机驱动系统转矩进行控制。仿真实验表明,本文方法能够大幅降低驱动系统转矩脉动,保证了开关频率恒定,实用性强。When the traditional method performs permanent magnet synchronous motor drive control,there are problems that the motor drive torque pulsates large and the frequency is not constant.For this reason,this article introduces sensorless control technol-ogy to control the torque of the motor drive system.Simulation experiments show that the method in this paper can greatly re-duce the torque pulsation of the drive system,ensure the constant switching frequency,and have strong practicability.
