摘　　要：永磁同步电动机作为机电能量转换设备,对其控制实质是电磁转矩的控制。矢量控制和直接转矩控制可以实现电动机全速域下工作,如何满足不同性能要求,电动机工作特性是根本依据。本文从数学模型分析比较两种控制方法的基本原理,从中可看出电机不同运行状况时的电磁关系及对转矩的影响。同时,介绍了电压型逆变器的调制技术,为利用和改善电机工作提供综合思路。Acting as an electromechanical energy conversion equipment,the PMSM control is electromagnetic torque control in essence.The PMSM is run in full speed range using FOC and DTC,the operating characteristics of PMSM is fundamental basis for the different performance requirements.The fundamental principle of the two control methods is analyzed and compared from mathematic model in the article,the electromagnetic relationship and its effect on torque are concluded under different operating conditions.Moreover,the modulation technique of VSI is introduced,providing a comprehensive idea for utilization and improvement of PMSM.
