摘要
针对基于直接转矩控制的异步电动机运行时存在较大的电流及转矩脉动问题,给出一种新型的异步电动机直接转矩控制系统,以减小异步电动机的电流及转矩脉动。仿真结果表明,该系统能有效地解决电流及转矩脉动的问题。
In view of the high electric current and the torque pulsation problems when the asynchronous motor running based on the direct torque control,a new asynchronous motor direct torque control system was proposed,which reduced the electric current and the torque pulsation of the electric motor. The simulation results indicated that this method could effectively solve the problems of electric current and of the torque pulsation.
