Drive Control Technology of Dual Three Phase Permanent Magnet Synchronous Motor for Electric Propulsion Aircraft

Abstract

Green aviation is one of the effective ways to cope with future oil energy shortages and improve the atmospheric environment. As the executing mechanism of electric propulsion aircraft, the fault tolerance and safety of the electric drive system are the primary considerations. This article uses dual three-phase permanent magnet synchronous motors (PMSM) to drive propellers to provide power for electric propulsion aircraft. Firstly, the working principle of the propellers is analyzed, and a simulation model of the propellers is established using Simulink; Secondly, the space vector control method of dual three-phase PMSM is elaborated, and two different forms of space vector control are compared. At the same time, a vector control model of dual three-phase PMSM is established, and the third harmonic content of dual three-phase PMSM under two different space vectors is compared through simulation. Finally, establish a simulation model of dual three-phase PMSM driving propeller, compare the motor phase current and driving performance of different vector control methods, and analyze the advantages and disadvantages of different vector control methods.
