考虑边缘效应直线感应电机矢量控制系统仿真

The Vector Control of LIM by Adding the End Effect Function

考虑直线感应电机的动态纵向边缘效应,建立直线感应电机数学模型。利用Simul建立了矢量控制模型,对考虑与不考虑动态纵向边缘效应的仿真结果作了对比,结果证明了考虑边缘效应的正确性与有效性。

The dynamic vertical end effect of linear motor is analyzed, which causes eddy current loss and air gap flux decrease. An equivalent circuit model in the rotor flux oriented frame is developed for the vector control of LIM by adding the end erect function. The simulation results show the improvements achieved by the proposed scheme.
