Abstract :
This paper presented a novel, practical high performance control scheme of interior permanent magnet synchronous motor (IPMSM) for Hybrid Electric Vehicle ( HEV) application. The control scheme improves the speed dynamic consistency in full range operation by adding torque loop in the speed control system. It adopts zero space vector time T0 feedback instead of full voltage feedback to generate an adequate flux-weakening (FW) current. It simplifies the nonlinear computation of the full voltage reference and can adapt the change of DC bus voltage fed by fuel cell automatically. It is convenient to select torque control mode or speed control mode. It can be easily implemented in software without additional hardware or sensor needed. The simulation and partial experimental results show the good feasibility and performance of the proposed control scheme.
