N2 - In this paper, a model predictive current control (MPCC) strategy is proposed for a novel dual-armature winding dual-permanent magnet machine (DWDM), aiming to reduce harmonic currents and torque ripples. The DWDM features 5phase stator windings and 3-phase rotor windings, with Halbach-array permanent magnets embedded in both stator and rotor slots. Owing to the configuration of armature windings and permanent magnets in both stator and rotor, the novel DWDM is capable of outputting array-distributed torque components. Based on the mathematical model of the DWDM, the proposed MPCC enables direct control over the machine's current components without the need for current loops or pulse width modulation. However, due to the unique mathematical properties of the DWDM, conventional MPCC results in significant harmonic currents in both the 5-phase stator windings and 3-phase rotor windings. To address this issue, an improved cost function is proposed for the MPCC strategy, which effectively reduces harmonic currents in both stator and rotor windings. Simulation results verify the effectiveness of the proposed method.
