摘要
根据直接转矩控制原理及特点,建立起一种适合大功率异步电动机的直接转矩控制系统的仿真模型,具体描述了系统的控制策略、新坐标轴系的选择、实现最佳开关状态方法以及正确判断区域和平滑过渡方法。仿真结果验证了控制方法的有效性和正确性。
In the light of the principle and features of the direct torque control （DTC）, a simulation model of DTC system for high power asynchronous motor is built. It is described in details the system control strategy, selection of the new axis, the realization of optimized switch state, correct judgment of areas, as well as smooth transition method.. The simulation results show validity and correctness of the control method.
