摘要
Abstract
Aiming at the problems of large torque ripple and unfixed switching frequency in the conventional direct torque control,which limits the application of engineering,a kind of permanent magnet synchronous motor direct torque control scheme based on SVPWM technique was proposed. Taking the new structure of the single torque loop of DTC system as a basis,used SVPWM instead of the traditional switch table method,and also improved the torque regulator. The validity of the theory analysis and the feasibility of the system are verified by the experiments.关键词
