Abstract: This article studies the servo system of surface-mounted permanent magnet vernier motor, designs a servo control system controller with a motor three-loop ( i. e. current loop, speed loop, position loop) structure, and analyzes the dynamic and static performances of the servo system. A co-simulation model of a surface-mounted permanent magnet vernier motor servo control system was established using Maxwell, Simplorer, and MATLAB / Simulink software, and the influence of position loop parameters on the rapidity and accuracy of the position following system was studied. A comparative analysis was conducted on the field circuit coupling simulation and constant parameter simulation of the three-loop structure servo control system. The simulation results show that this control strategy can achieve precise positioning of PMVM without overshoot, and has good speed and anti-interference performance.
