摘　　要：采用解析-有限元混合法获得单初级PMLSM稳态运行时的磁场分布,利用后处理的磁链数据作为PMLSM磁链模型的非线性回归分析样本;采用支持向量机实现对磁链的非线性函数的逼近,改变PMLSM运行工况检验非线性磁链模型的正确性,采用此模型研究PMLSM的稳态特性,并对结果进行定性分析,给出合理的解释。在此非线性模型的基础上经过扩展可以得到多初级分段永磁直线同步电机模型。A single primary PMLSM （permanent magnet linear synchronous motor） field distribution in steady state condition was attained by analytical solution - FEM hybrid method. Took the post-process data of PMLSM flux linkage as sample of nonlinear regression, and adopted support vector machine （SVM） to approach flux linkage nonlinear function, whose valid was verified by changing PMLSM operation condition. The PMLSM steady states characteristics were analyzed with the flux linkage model, qualitative analyzed the results cause and gave the reasonable account. DP- PMLSM nonlinear model was attained by extending a single primary PMLSM nonlinear model based on wingding flux linkage.
