Abstract :
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.
