Abstract:
This paper proposes an innovative control algorithm for Permanent Magnet Synchronous Machines (PMSMs), based on a Vector Current Control (VCC) strategy in order to operate in the Flux-Weakening (FW) zone and a Finite Element Analysis (FEA) to consider the cross-saturation effects. The proposed algorithm can be easily adapted either with or without the cross-magnetization outcome. The control algorithm includes the variation of the dq-axis inductances in the optimized problem of calculating the dq-axis currents from the torque setpoint. The simulation results verify the worthiness of the proposal for a 2.5 kW Surface Permanent Magnet Synchronous Machine (SPMSM) direct-drive e-motorbike.
