采用支持向量机拟合了通过磁场计算得到的永磁同步电动机的非线性数值模型,充分考虑了电机铁心饱和以及电机磁感应强度非正弦分布所引起的非线性因素,同时建立了基于该非线性模型的永磁同步电动机的SVM-DTC系统的仿真模型,为永磁同步电动机的优化设计、性能分析及控制算法的研究提供了有效的工具.%Support Vector Machine (SVM) was used to fit the nonlinear-model,which is gained by magnetic field computation,for permanent magnet synchronous motors (PMSMs).Nonlinear factors caused by saturable core and non-sinusoidal distribution of induction density were taken into consideration.A simulation model was also built for SVM direct torque controlled PMSM drive system on this nonlinear-model.The system offers an effective tool for the optimization design, performance analysis and research on the control algorithm.
