Abstract: In order to improve the power density of the traditional aviation three-stage starter / generator power generation control system,this paper proposes a new aviation two-stage starter / generator voltage-stabilized power generation control system. The topological structure and working principle of the system are expounded,and the mathematical model of main motor and exciter with 75 kVA power level in d、q coordinate system is deduced. The according to the control strategy of stabilized voltage generation, combined with the idea of direct current side parallel self-excited excitation system, the voltage-current double closed-loop proportional-integral-derivative simulation model of regulated power generation control
system is established. The simulation analysis was conducted,and the results indicated that the two-stage starter / generator can automatically switch to the appropriate excitation mode during sudden load changes,achieving stable voltage operation under both light and heavy load conditions.

Key words: two-stage starter / generator, stabilized power generation control, self-excited system, direct current side parallel self-compound excitation
