| Abstract: | The direct-torque control strategy for asynchronous electromotor based on matrix converters is studied.The principle of direct-torque control,the space vector modulation of matrix converter(MC)and the selection of MC space vector voltage based on direct-torque control are systematically analyzed.Realization of this strategy based on MATLAB and the simulation results are given in this paper,which verify that this control strategy results in good static and dynamic performance of speed control system,and maintains the unity power factor. |
