建立了表面式永磁同步电动机的模型,并对损耗进行了分析。在此基础上,对其损耗进行了降阶化处理,使得复杂的四次多项式转化为一次方程,从而大大简化了计算难度,省去了大量时间,并提高了研究效率。通过MATLAB仿真平台,在Id=0的情况下,通过矢量控制的方法得到相关电流值,从而对电机的效率进行了拟合,验证了降阶处理的合理性。
A model for surface mounted permanent magnet synchronous motor was established. The analysis for its los-ses was made. Furthermore, after several steps, the fourth-order polynomial of the optimal control method was simplified to first-order equation that can simplify and save time. By using the vector control method under Id =0 ,the simulation of MAT-LAB was done to verify the rationality of the reduced order processing.
