| 摘 要： | 针对基于电感的永磁同步电机(PMSM)线性集中参数模型无法描述电机磁路饱和、反电动势非正弦等非理想特性的问题,提出一种基于磁链重构的PMSM分布参数模型,并进行了仿真和试验验证。首先通过有限元分析(FEA)获取电机不同工作点下的磁链,其次利用傅里叶级数展开和多项式拟合方法对磁链进行重构,再根据重构的磁链建立起PMSM分布参数模型,并进行了仿真和试验验证。仿真和试验结果表明,模型能准确描述PMSM在不同工况下的非线性特性。

| Abstract: | Aiming at solving the problem that the linear lumped parameter model of permanent magnet synchronous motor (PMSM) based on inductance cannot describe the nonideal characteristics, such as magnetic saturation and nonsine back electromotive force, a distributed parameter model of PMSM based on flux linkage reconstruction was presented, and the proposed model was verified with simulation and experiment. In detail, first of all, the flux linkage of different working points of the motor was obtained by finite element analysis (FEA). Secondly, the flux linkage was reconstructed by Fourier series expansion and polynomial fitting method, and then the distributed parameter model of PMSM was established according to the reconstructed flux linkage. Finally, simulation and experiment were carried out for verification. Simulation and experimental results showed that the model could accurately describe the nonlinear characteristics of PMSM in different working conditions. |
