异步电动机S函数仿真模型研究

Study of S Function Simulated Model of Induction Motor

根据异步电动机的转子同步旋转dc-qc-0坐标系下的数学模型,推导出基于MATLABSIMULINK工具箱中的S函数的异步电动机仿真模型,实现了对异步电动机的起动过程的仿真.对于异步电动机基于dc-qc-0坐标系下的动态模型,以定、转子电流做为状态变量,用MATLAB中的S函数求解微分方程.对异步电动机的仿真结果验证了模型的正确性.该方法构造方便,实时性好,可移植性强,且具有很强的扩展性.

This paper introduces an induction motor dynamic model based on rotor synchronization rotated reference frame and deduces induction motor simulated model by using the tools of S function.Starting process simulation of induction motor is realized in this paper.The dynamic model of induction motor based on d_c-q_c-0 is described by a set of differential equations whose state variable is stator and rotator current.Using S function of simulink tools,model of induction motor is expediently simulated.This method is more simple,expedient,real_time and expansibility is of strong.
