Research on Design and Control Strategy of Multi-winding PMSM for Solar-powered UAV

A novel multi-winding permanent magnet synchronous motor (MWPMSM)suitable for distributed energy management systems is proposed to meet the endurance requirements of near-space solar-powered Unmanned Aerial Vehicle (UAV). The system consists of three sets of windings, with each set of windings and its corresponding driver constituting a motor module. One of the motor modules adopts vector control to obtain a set of reference current phases, while the other motor modules adopt a quasi-PR control strategy to track the reference current phase. In this system, the different motor modules can work independently as well as cooperate with each other. The experimental results show that the winding currents of each motor module can ensure phase synchronization, validating the rationality of the MWPMSM control strategy for solar powered UAV and the feasibility of implementing the quasi-PR control strategy.
