To meet the satisfy the safety redundancy demands of all-electric aircraft. This paper analyzes the redundancy characteristics of the dual three-phase permanent magnet synchronous motor (DTP-PMSM) and proposes a dual-redundancy cooperative control strategy. The windings of DTP-PMSM are divided into two groups of three-phase windings, each of which is independently controlled by a controller. When one set of windings fails, the motor can maintain stable operation utilizing the remaining healthy windings. The dual redundancy design improves the safety and reliability of the all-electric aircraft. A dual-redundancy model is built to simulate the proposed control strategy. Finally, experimental verification is carried out. Through simulation analysis and experiments, the viability of the presented control scheme is substantiated.
