Flux Weakening Control Technology of Multi-phase PMSG for Aeronautical High Voltage DC Power Supply System

Abstract

Aiming at the problem of large voltage change of generator output port caused by wide speed operation of aeronautical power supply system, the method of combining id=0 vector control and flux weakening control with single current regulator is used to satisfy the HVDC power supply requirement of 270V by selecting the control mode switching under different states. Finally, on the basis of the mathematical model of dual Y shift 30 degree PMSG, the feasibility of this method is proved by simulating and analyzing the change of its speed and load on Matlab/Simulink model.
