摘　　要：直接转矩控制(DTC)借助于滞环调节器产生脉冲信号,直接对逆变器的导通状态进行最优控制,以获取转矩的高动态性能,并省去了复杂的矢量坐标变换.具有动态响应迅速,控制简单,易于实现等优点.本文采用自行设计的电压开关矢量表,建立了异步电动机直接转矩控制系统的基于MATLAB的仿真模型.仿真结果表明,所设计的直接转矩控制系统是正确的.Direct Torque Control generates pulse signal with Hysteresis regulator,controls the inverter-state of optimum directly to obtain high dynamic performance of torque and eliminates the need for complex vector coordinate transformation,with rapid dynamic response,simple control,and easy implementation.The simulation model of DTC was set up by using the self-designed voltage switch vector table with the soft of MATLAB.According to the result of the simulation,the model designed in this paper was proved correct,and the result was satisfying.
