开关磁阻电机作为一种电动调速系统具有结构简单坚固、低成本、高容错性能以及高速运行的能力,目前它越来越广泛的应用于航空和汽车上的起动/发电系统,具有很大的潜力。要对开关磁阻电机进行深入的理论分析,就需要对其建立一个准确而又有实用性的模型。而 MATLAB 软件具有强大的矩阵和数学计算功能,利用它的模块之一 SIMULINK 建模有着界面友好、易于进行参数修改等特点。国内利用 MATLAB 软件对开关磁阻电机进行建模主要分两大类:一部分是采用 M 文件编程的方法 另一部分是利用开关磁阻电机的线性电感模型或者准线性模型进行建模分析。两者都没充分利用MATLAB/SIMULINK 的主要功能。 本文将基于 MATLAB/SIMULINK 对开关磁阻电机进行非线性建模研究。-Switched reluctance motor as an electric control system has a simple structure robust, low cost, high fault tolerance and high-speed operation capability, now it is increasingly widely used in aerospace and automotive starter/generator system, with great potential. To SRM-depth theoretical analysis, we need to have their precise and practical to build a model. The MATLAB software has powerful matrix and mathematical calculations, use one of its modules, SIMULINK modeling has friendly interface, easy to modify the parameters and so on. Domestic use of MATLAB software to model the SRM two main categories: one is programming method using M files　the other part is the use of switched reluctance motor or a linear inductance model to model quasi-linear model analysis. Both did not make full use of MATLAB/SIMULINK s main functions. This will be based on MATLAB/SIMULINK for nonlinear modeling of SRM research.
