This article studies the basic principle of Three Vector Model Predictive Current Control(TV-MPCC)and analyzes the calculation method of the optimal voltage vector action time that minimizes the current cost function.The finite element model,driving circuit model,and TV-MPCC module of the permanent magnet vernier motor are established by ANSYS Maxwell,Simplorer,and Simulink respectively,and the three parts are combined to form a field circuit coupling simulation model.The performance differences between TV-MPCC and field oriented control(FOC)strategies based on coupling simulation.The differences between coupling simulation and fixed parameter simulation by TV-MPCC were compared and analyzed by simulation experiments.The results indicate that TV-MPCC can be applied to permanent magnet vernier motors to improve the speed of current response,reduce its overshoot,and the field circuit coupling simulation results are more accurate than the fixed parameter simulation when the motor operates under high torque.
