Abstract :
In order to improve the performance of DTC at low speed and reduce switching frequency at high speed, a method that uses circular flux control model when the measured speed is no more than 10 percent of the rated speed and hexagonal model at higher speed is researched in this paper. Simulation based on this method is given on the platform of MATLAB. The simulation results indicate it can improve low speed performance, reduce switching losses and can run smoothly in the speed range.
