基于Matlab/Simulink的异步电机直接转矩控制系统仿真

Simulation of Asynchronous Motor Direct Torque Control System Based on Matlab/Simulink

对Simulink自带的电机模块存在的问题进行了阐述。在异步电机数学模型的基础上,利用Matlab/Simulink软件建立了电机模型和直接转矩控制系统模型。详细介绍了系统的主要模块。通过仿真实验,得到了定子磁链、定子电流、转速、转矩的仿真波形,验证了控制策略的正确性。

The disadvantage of the electric machine block of Simulink is described in this paper. The mode of motor and direct torque control system are constructed by Matlab/ Simulink based on the mathematic module of asynchronous motor. Some key blocks of system are introduced in detail. The waveform of stator flux, stator current, speed, torque are given through simulation text. The results proved that the method is available.
