Novel decoupling model predictive current control strategy for flux-switching permanent magnet synchronous machines with low torque ripple and switching loss

Flux-switching permanent magnet machine (FSPMM) is a new doubly salient permanent motor which has inherited the advantages of doubly salient permanent magnet (DSPM) and reluctance motors switched reluctance machine (SRM). With the good merits of high torque density, strong mechanical robustness, fault redundancy ability, etc., FSPMM has found great potential applications in transportation, electrical airplane, ship, and so on. However, it suffers large torque ripple and switching losses for the uniqueness of the stator and rotor. In this paper, a novel model predictive current control (MPCC) algorithm is proposed for reducing the torque ripple and switching losses. An improved modulation strategy, Cost Function, has been used to look for the best switching vector and the most ideal switching frequency for the drive converter. Comprehensive theoretical and simulation analysis has validated the innovation feasibility.
