摘要/Abstract

摘要：

针对初级绕组分段永磁直线同步电机所特有的分段供电问题,文中采用空间矢量解耦的方法,搭建了初级绕组分段式永磁直线同步电机的数学模型,并在此基础上搭建了一种可以对初级绕组进行分段供电的矢量控制模型。通过比较分析每段初级绕组所产生的合力与运动体和单段初级绕组全部耦合时所产生的推力是否相等,判断所搭建的模型的准确性。在MATLAB/Simulink环境下进行仿真,结果表明运动体在段间和段内所受到的推力相等。该结果说明所搭建的模型可以有效、快速反映动子位移,实现精准绕组切换,达到分段供电的目的。

Abstract:

Aiming at the special sectional power supply problem of primary winding segment permanent magnet linear synchronous motor, the mathematical model of primary winding segment permanent magnet linear synchronous motor was constructed by space vector decoupling method. In addition, on this basis, a vector control model for primary winding segment power supply was established. By comparing the resultant force produced by the primary winding of each element , the thrust produced by the coupling of the moving body and the primary winding of a single segment, the accuracy of the model was judged. The simulation experiments were carried out under the environment of MATLAB/Simulink. The results showed that the thrust of the moving body was equal between segments and within segments. Therefore, the model built could reflect the displacement of the mover effectively and quickly, realized precise winding switching and achieved the purpose of sectional power supply.

Key words: winding segmentation, PMSLM, MATLAB/Simulink, vector control, winding switching, simulation verification, piecewise power supply
