摘要

本文介绍了一种基于SVM-DTC的异步电动机控制方案。将空间矢量调制(SVM)和直接转矩控制(DTC)相结合，与传统的直接转矩控制相比，产生最小的转矩波动。实验验证了异步电动机在基本转速范围内和弱磁场范围内的转速和转矩性能。采用“1/ ωr”法对弱磁区定子磁通进行弱磁。整体实验采用基于TMS320F28335浮点微控制器的驱动系统，以测功机作为电机负载。

SVM Direct Torque Control of an induction machine

This paper describes an SVM-DTC control scheme of an induction motor. Combining the Space Vector Modulation (SVM) and Direct Torque Control (DTC) resulting a minimal torque ripple compare to classical DTC. Investigation of speed and torque performance of the induction motor within base speed and in field weakening region are verified in the experiment. The stator flux in field weakening region is weaken using “1/ ωr” method. The overall experiment is conducted using a drive system base on TMS320F28335 floating point microcontroller and dynamometer as a load of the motor.
