摘　　要：传统永磁同步电机应对负载突变干扰能力较弱,为了提高系统的抗干扰能力,改善系统的驱动控制能力,提出一种基于转矩反馈补偿的最大转矩电流比(MTPA)控制方法来抑制永磁同步电机转速和转矩脉动。根据负载转矩与电磁转矩的差值对MTPA的电流进行补偿,在维持MTPA控制效率优势的同时,改善转速调节器在转速脉动抑制方面的不足,抑制转速波动与电磁转矩脉动,提高控制系统的抗干扰能力。实验结果验证了所设计控制方法的有效性。In order to improve the anti-interference ability of the system and improve the drive control ability of the system, a maximum torque-to-current ratio(MTPA) control method based on torque feedback compensation was proposed to suppress the permanent magnet synchronous motor with magnetic synchronous motor speed and torque ripple. The current of MTPA was compensated according to the difference between the load torque and the electromagnetic torque. While maintaining the advantage of MTPA control efficiency, the shortcomings of the speed regulator in the suppression of speed pulsation were improved, the speed fluctuation and electromagnetic torque pulsation were suppressed, and improved the anti-interference ability of the system. The experimental results verified the effectiveness of the design control method.
