An interior permanent magnet synchronous machine (IPMSM) offers high-power density and can operate over a wide speed range which makes it an attractive option for electric vehicles. Furthermore, it is more mechanically robust in comparison to a surface-mounted permanent magnet synchronous machine (SPMSM) due to the magnets being embedded within the rotor. Electric vehicles tend to operate at low ratios of switching-to fundamental frequency which can lead to challenges from a current control perspective. This thesis investigates control algorithms for IPMSMs when operating at a low ratio of switching-to-fundamental frequency. This work first examines the conventional scalar current control approach used and identifies its shortcomings. It then proposes an alternative current controller that has the potential to improve performance at low frequency ratios. A complex vector model of an IPMSM is derived in order to design the proposed complex vector controller.
