摘要
推导出在转子磁场定向控制中两相同步旋转坐标系下不考虑铁损和考虑铁损的三相异步电机动态数学模型,进而建立基于Simulink的不考虑铁损和考虑铁损的三相异步电机仿真模型。用仿真实例比对两个模型,验证了考虑铁损的异步电机模型在磁场定向时能更真实地反映电机实际物理过程,为异步电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。
Deduce the dynamic mathematical model of asynchronous motor with iron loss and the model without iron loss in towphase synchronous rotation frame and Rotor flux oriented control,and with Simulink establish the simulation model of three phase asynchronous motor with iron loss and the model without iron loss. Compared the tow models with simulations,the simulation results demonstrate that the model with iron loss is closed to reality of asynchronous motor in rotor flux oriented,the proposed high-efficient model provides a more accurate approximation.to actual asynchronous motor for many control problems of asynchronous motor drives.
