Speed Regulation System of Permanent Magnet Synchronous Motor Field Weakening Control Based on Model Predictive Control

Abstract

The paper is based on the theoretical analysis of motor field weakening control, design field weakening control system based on voltage feedback. In this research, MPC control algorithm is introduced into speed loop. Under field weakening control strategy, the designed MPC controller is applied to motor control system. Finally, the simulation results show: under field weakening control, MPC controller has better robustness and stronger anti-interference ability than PI controller, which improves system stability.
