摘要
该文对交流异步电机变频调速的建模与仿真进行了研究。在几种常见的电机控制方式中,最终选定了转差频率控制方式的变频调速技术。文中给出了电机数学模型的详细构建过程,并以此为基础结合采用MATLAB SIMULINK软件包得出了电机的动态仿真模型。试验的结果显示,该模型更为简单、实用并且具有很好的可扩展性,从而方便的用于其它的控制系统中。该模型曾经在恒压供油系统仿真中使用,并取得了满意的试验结果。
This paper is devoted to modeling and simulation of induction motor. Slip frequency as a technique of frequency conversion is finally adopted among several control methods of motor. This article also shows the process of mathematical modeling for motor in more detail, based on which MATLAB SIMULINK is used to get the final dynamic model. This simple but practical model presents its ideal expansibility in the results of experiment. Satisfactory results are also acquired when this model is installed in Constant Pressure Supply Oil System.
