Interior Permanent Magnet Synchronous Motor(IPMSM) has gained an increasing popularity in recent years for Hybrid Electric Vehicle(HEV) and Electric Vehicle(EV), because of their high power density and high efficiency. This paper proposes a current reference generation method based on electric machine flux model, and compares the performance of the proposed method with those of a conventional method. Experimental results showing the superiority of the proposed method are provided in this paper.
