IPMSM control regime for a hybrid-electric vehicle application

Abstract

Due to its high torque density, the interior permanent magnet synchronous machine (IPMSM) is nowadays often used in electric vehicle applications. For an efficient machine operation, a proper control strategy has to be implemented. Because of the inherent non-linearities, the control is often based on lookup tables covering the entire operating area. The proposed control strategy relies on lookup tables only containing points on the edges of the operating area. This minimizes storage requirements and determination effort, while maintaining a sufficient level of accuracy.
