摘　　要：介绍了异步电动机直接转矩控制系统的基本结构和原理,在此基础上分析了低速运行时的圆形磁链控制方法.采用异步电动机α-β坐标系下的数学模型,按照磁链的圆形控制方法,基于MATLAB6.5/Simulink5.0构建了仿真模型,给出了仿真结果及分析.仿真结果验证了该模型的正确性和该控制方法的有效性.This paper demonstrates the basic structure and the working principle of the direct torque control system of an asynchronous motor and studies the control method of round flux linkage trace of low-speed running. Furthermore, a simulation model is built up based on MATLAB6.5/Simulink5.0 according to the mathematical model of asynchronous motor in α-β coordinate system and the control method of round flux linkage trace. The results show that the simulation model is right and the control method is effective.
