摘　　要：基于电力牵引系统中异步电动机直接转矩控制的基本数学模型,建立了该种异步电动机直接转矩控制系统的Matlab/Simulink仿真模型。通过数值仿真证明了直接转矩控制的优越性。According to the basic mathematical formulas of Direct Torque Control （DTC）, a simulation model of DSC of asynchronous motor is proposed in electric traction system. The system is simulated using Matlab/Simulink software, and the results show that DTC has a lot of advantages, including faster response, shorter transient time, smaller fluctuation and invariable amplitude when load and rotational speed vary., smaller effect when rotor parameter vary, all above prove that DTC has superiority and availability.
