Abstract: Unmanned Aerial Vehicles (UAVs) have high safety and reliability requirements for the driving of the motor. The use of the dual-winding Permanent Magnet Synchronous Motor (PMSM) with redundant fault-tolerant structures is an effective method. However, when the drive fails, the reliable control of the motor is affected. Therefore, a modular peer-to-peer control strategy based on the three-phase winding unit is proposed. Each unit motor is equipped with an independent controller to form a dual redundant structure of the controller and the motor winding. The speed droop control method is adopted to realize the cooperation of two control modules, and the slope can be adjusted to achieve the output power sharing of the unit motor. To improve the accuracy of speed control and power sharing the secondary adjustment control scheme is adopted. A mathematical model of the system under droop and secondary regulation control is established to analyze the stability of the system. Simulation and experiments are conducted to verify the effectiveness of the proposed method, which can achieve cooperative operation of two unit motors, and complete speed regulation and power sharing.

Key words: modular motor drive, dual-winding permanent magnet synchronous motor, speed-droop, power sharing, secondary regulation
