Simulation Research on direct torque control of permanent magnet synchronous motor based on SVPWM

Abstract

The traditional direct torque control is mainly based on the stator flux vector value to achieve the purpose of stator torque control. The most effective way is to change the double hysteresis structure of stator and torque flux. Although the structure of this control mode is relatively simple and the torque can respond quickly, it will lead to serious torque and speed fluctuations. In this paper, the SVPMSM technology is introduced to replace the original voltage vector selection module, and the MATLAB/Simulink simulation model is built. The results verify the effectiveness of the direct torque control algorithm.
