摘　　要：感应电机直接转矩控制中磁链和转矩滞环幅值在很大程度上影响着控制系统的稳态性能。首先介绍了直接转矩控制基本原理,然后利用在Matlab/Simulink平台上建立的异步电机的直接转矩控制仿真模型,仿真分析了磁链滞环容差和转矩滞环容差对定子电流和电机转矩的影响,给出了仿真结果,为进一步改善系统性能以及投入实际应用奠定了基础。In direct torque control of induction motor, the flux and torque hysteresis width greatly influence the stable state performance of the control system. The basic principle of direct torque control was introduced. Then made use of the simulation model of the direct torque control system based on Matlab/SimuLink,anaLysed the influence of the flux and torque hysteresis width to the pulsations of stator current and torque of induction motor. The results of simulation are given, which are helpful for improving the performance of the systems.
