Cooperative control strategy with ring coupling for DTP-PMSM aviation electric propulsion system

Distributed electric propulsion systems offer advantages such as high thrust and high control flexibility, making distributed electric propulsion aircraft a leading direction for future green aviation. The dual three-phase motor control system possesses a large capacity and outstanding fault tolerance, presenting significant advantages in aerospace electric propulsion systems. Distributed aerospace electric propulsion systems impose strict requirements on synchronous power distribution across the two wings. The cooperative control strategy for multi-motor systems studied in this paper enables the electric propulsion system to maintain synchronous operation in the presence of external disturbances, thereby reducing the impact of uncertain disturbances on synchronization performance and enhancing flight safety.
