笼型异步电机的建模及SIMULINK仿真

依据异步电机在M、T坐标系中的数学模型,构造出其动态仿真模型。在此模型中,避开了求导环节,所以此模型具有较强的稳定性。将MATLAB提供的仿真环境SIMULINK应用于此模型,验证了仿真模型的正确性,并且能方便地显示电机内部的物理量。以此模型为基础,可构成各种控制系统,研究各种控制策略,具有一定的实际意义。同时可以看到,SIMULINK实现了全图形仿真,省去了以往仿真研究中的大量手工编程过程,大大地提高了仿真效率和可靠性,具有直观、方便、灵活、精度高等优点,在控制系统中确为先进而优秀的软件。

Modeling of Squirrel-Cage Induction Motor and SIMULINK Simulation

This paper established a dynamic simulation model of squirrel-cage induction motor according to it's mathematics model in M、T coordinate system. The simulation model has virtue of strong stability because there is no any derivation step in the model. This model can provide more physical parameters of the model. The correctness of this model was proved through applying the simulation enviroment SIMULINK provided by MATLAB to this model. Various control systems can be constructed and various tactics can be studied based on the model. It has certain practice meaning. At the same time, we can see that SIMULINK can realize total plots simulation and save handwork procedure and greatly raise simulation efficiency. It has audio-visual, convenient, flexibility. It is indeed advanced and excellent simulation software in control systems.
