Abstract
An integrated starter/generator based on the wound-rotor synchronous machine is becoming increasingly popular in modern aircraft due to the advantages of high safety and low cost in maintenance. Constant field current for the main generator of the wound-rotor synchronous starter/generator (WRSSG) can simplify the start control scheme distinctly in the starting mode. In order to achieve constant field current for the main generator, three detailed excitation control methods for the two-phase brushless exciter of the WRSSG in the starting mode were proposed and compared in this paper. And in these excitation control methods, feedback control for the field currents of the two-phase brushless exciter and speed reference control for the excitation frequency and phase sequence were adopted. Simulation and experimental results verified the feasibility and effectiveness of these three excitation control methods.
