摘　　要：在异步电机数学模型的基础上,建立了异步电机直接转矩控制模型。对控制的原理做了简要说明,详细介绍了系统主要模块,并改进了电机定子磁链观测模型。利用Matlab/Simulink软件进行仿真实验,得到定子电压与电流、转矩、转速及定子磁链的仿真波形,验证了控制策略的正确性。The mode of direct torque control（DTC） for asynchronous machine is constructed based on the mathematic module of asynchronous machine.The paper explains the principle of control methods.Some key blocks of system are introduced in detail,and the block of stator flux observation is improved.At last an experiment with constant parameters is emulated by Matlab / Simulink software and the waveforms of stator voltage,stator current,rotor speed and electromagnetic torque are given,and the results prove that method is available.
