考虑铁损的感应电动机仿真模型研究

Modeling and Simulation of Induction Motors Considering Iron Loss

推导了感应电动机在同步旋转坐标系下考虑铁损的状态方程,将状态和参数分离开来,用MATLABCMEX文件S函数建立了考虑铁损的变参数感应电动机仿真模型,用仿真实例验证了模型的正确性、有效性和快速性,为感应电动机的控制问题提供了一个更加接近电机行为特性的高效仿真模型。

A state equation for induction motors considering iron loss in the synchronous frame was developed in order to separate the states and the parameters of induction motors. Then, the simulation model of the motors with iron loss and variable parameters was established based on a MATLAB C MEX-file S-function. The validity, effectiveness and speediness are verifed by simulations. The proposed high-efficient model provides a more accurate approximation to actual induction motors for many control problems of induction motor drives.
