摘　　要：介绍一种典型的直接转矩控制系统.针对传统的电气传动控制系统仿真建模复杂、计算量大等不便,根据直接转矩控制原理,利用Matlab/Simulink软件对异步电动机直接转矩控制系统进行建模和仿真.Simulink具有良好的用户界面和强大的功能,在该环境下结合电气系统模型库进行仿真,具有建模简便、结构直观、操作灵活等优点.并给出用Matlab/Simulink对该系统进行仿真的方法和结果.对仿真结果的分析表明,直接转矩控制策略具有良好的控制性能.The paper presents a typical DTC system. Considering the inconvenience of modeling and calculation in the traditional simulation model of torque control system, a simulation model of torque control system in the simulink environment of the Matlah simulation software is proposed. Combined with power system Block set , the system can be easily modeled, the operation is flexible. The typical DTC system is introduced, the method and result to simulate the system in Matlab/Simluink are given. Through analyzing the simulation results, it can be seen that the strategy of Direct Torque Control has good control performance.
