Fast-Speed Drives for Permanent Magnet Synchronous Motor Based on Model Predictive Control

Fast speed-tracking with limits commitment for currents and voltages of drivetrain is crucial for EV/HEV. This study proposes a fast-speed drive for permanent magnet synchronous motor (PMSM) based on Model Predictive Control (MPC). Fast speed tracking is achieved through optimization of the DC source utilization. With common torque and current limits, the proposed technique predicts the optimum voltage vector applied to the driver. The performance of the PMSM under Field Oriented Control (FOC) and MPC is first analyzed by a simulation study at different working circumstances. The effectiveness of the proposed MPC has been validated by simulation results. Then, an experimental setup has been established for the PMSM drive using a TMS320F2812 DSP. The effectiveness of the proposed MPC has been validated by experimental results. With simulation and experimental results, the presented MPC has been investigated by comparing to the cascaded PI control based on SVPWM to highlight the improvements, especially regarding speed tracking response.
