Abstract Aeronautic variable frequency(VF) AC generation system has been paid more and more attention. The variation of the generator characters keeps along with the variation of generator speed, and brings challenge to the voltage regulator, because the exiting technology of the voltage regulator can not fit the VFAC generation system. In this paper, the multi-loop feedback control technology is proposed. The four parameters including generator voltage, magnetic field exciting current, voltage frequency, and load current are detected and feedback to form the multi-loop. The generation system also contains the hybrid excitation synchronous generator (HESG), which is a novel aeronautic brushless generator. The output characteristics of the HESG are also analyzed in detail. The experiment results verify the theoretic analysis and simulation.
