摘要

在混合动力汽车(HEV)中，内部永磁同步电机(IPMSM)经常进入磁饱和状态，导致电感发生变化，特别是q轴电感。从而降低了当前的控制性能，甚至使驱动控制系统变得不稳定。在Matlab/Simulink中设计并建立了考虑磁饱和的电机模型。仿真结果表明，考虑磁饱和的控制系统具有良好的驱动控制系统稳定性。该策略可用于全工况，满足混合动力汽车的系统控制要求。

Driving system stability analysis and improving of IPMSM

In the hybrid electric vehicle (HEV), the interior permanent magnet synchronous motor (IPMSM) often enters into the magnetic saturation, which leads to the variation of inductance, especially for q-axis inductance. So that degrades the current control performance, even the driving control system becomes no more than stability. A motor model with considering the magnetic saturation are designed and established in Matlab/Simulink. The simulation results show that control system with considering of magnetic saturation has good driving control system stability. This strategy can be used in the full operation region, which meets the requirement of the system control in the HEV.
