为实现混合动力汽车用起动发电一体化(Integrated Starter and Generator,ISG)永磁同步电机控制系统的优化设计与精确的仿真分析,提高ISG永磁同步电机控制系统的快速开发能力,提出了一种ISG永磁同步电机控制系统设计新方法。该方法基于定子电流最优控制策略建立控制系统模型,结合有限元法计算的ISG永磁同步电机饱和电感参数特性和功率器件特性,在Simplorer系统仿真平台上开展ISG永磁同步电机及其控制系统设计与仿真。样机的仿真结果与试验结果比较吻合,验证了该设计方法的可信性,并实现了ISG永磁同步电机控制系统的快速开发。

In order to carry out the optimal design and accurate simulation of ISG（ Integrated Starter and Generator） permanent magnet synchronous motor（PMSM） for hybrid electric Vehicles, and improve rapid development capability of control system of ISG PMSM, this paper proposes a new design method of ISG control system. On Simplorer simulation plat- form, the optimal current control strategy for ISG control system is carried out, which considers saturation inductance pa- rameter abstracted from FEA analysis and power device characteristics. The simulation results are close to the experiment results, which testifies the creditability of this approach, and realizes rapid development capability of control system of ISG PMSM.
