| 摘 要： | 介绍了基于永磁同步电机的交流伺服系统。针对直接转矩控制的脉动问题,进行了分析,提出了基于SVM-DTC的控制策略,该策略利用电子电压在定子磁链坐标系的分量控制电磁转矩和磁链,结合空间矢量调制控制逆变器开关,并基于DSP2812搭建了硬件实验平台,通过MatLab仿真和实验波形表明,SVM-DTC的控制策略可以有效减小转矩、磁链脉动。

| Abstract: | This essay introduces the ac servo system of the permasyn motor, and put forward a new control strategy based on SVM-DTC, aiming at the torque pulsation of the direct torque control(DTC). This strategy uses component of electron voltage in the stator flux linkage coordinate to control electromagnetic torque and flux linkage, integrating SVPWM to control the switch of inverter. Besides, hardware platform is built using DSP2812. According to the simulation of MatLab and the wave form of the test, SVM-DTC can reduce the fluctuation of torque and flux linkage. |
