Research on the Control Principle of Aircraft AC Starter/Generator

Abstract:

AC starter/generator is a new starting/generation dual-function technology applied to the aircraft. The previous pneumatic starter, brushed DC starter/generator or DC starter are replaced by the synchronous AC motor, thereby reducing the weight of airborne equipment effectively. Based on AC starter/generator driven by auxiliary power unit (APU) used on a certain type of aircraft, this paper mainly carries out the research on the composition of AC starter/generator system, starting process and its control principle, as well as demonstrates how the starting torque is controlled. Theoretical study shows that the torque can be precisely controlled through the control of the torque component of stator current when the rotor field oriented vector control strategy is adopted.
