Direct Torque Control Technology for Permanent Magnet Synchronous Motor Based on SVPWM

doi:10.16182/j.issn1004731x.joss.19-FZ0279

Abstract

Abstract: The traditional direct torque control technology of permanent magnet synchronous motor utilizes the results of torque and flux linkage hysteresis comparison, and directly controls the torque by looking up the voltage vector. Though this algorithm is simple, its current waveform distortion and torque ripple is more serious, which is very unfavorable for actual motor control. In this case, by analyzing the shortcomings of traditional direct torque control, SVPWM technology is introduced into direct torque control, and the original look-up table module is replaced by SVPWM module. A simulation model is established for comparative analysis in MATLAB/Simulink, PMSM direct torque control technology based on SVPWM can significantly improve the phenomenon of serious current distortion and reduce torque ripple. The test is carried out on the DSP motor controller and the feasibility of this control algorithm in actual motor control is proved.

Key words: permanent magnet synchronous motor, direct torque control, SVPWM, torque ripple
