基于MATLAB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

利用MATLAB所提供的电气系统模块库Simulink,构造了一个异步电机直接转矩控制系统,对系统的相关子模块进行了较为详细的介绍,并给出具体的结构图。通过对仿真系统进行实验,可以得到系统的磁链、转速等仿真波形。实验结果表明,该系统设计是有效的,可以根据此系统制作一个基于直接转矩理论的电机控制器。

Simulink as the electric system model library based on MATLAB was applied to design an asynchronous motor direct torque control （DTC） system, relative submodels of the system was introduced, and a actual framework was given out. From the experiment of the emulate system, can get emulate wave of the system, such as magnetic chain and rotor speed, the experiment result indicate the design is effective, can adopt the system to design a real motor controller based on DTC theory.
