Research on Model Predictive Current Control of Permanent Magnet Hub Motor for Electric Vehicles

This paper focuses on the high demands of electric vehicle distributed wheel hub motors for dynamic torque and speed adjustments. It explores the application of a single-vector model predictive current control (MPCC) in permanent-magnet wheel hub motors to enhance their dynamic response. The study also optimizes the MPCC objective function while considering inverter voltage and current constraints, ensuring the optimal voltage vector complies with these limits. Finally, simulations demonstrate the superiority of the proposed MPCC method compared to traditional PI current loop control.
