Research on the Design Method of the Starting Process of Main Fuel Control system for Aviation Auxiliary Power Unit

摘要

This paper analyzed the main fuel control system of the auxiliary power unit (APU), explored the starting process of the main fuel flow control system control law and control algorithm. Focus on analyzing the interpolation table that is involved in the controller of the starting process, restoring its physical meaning. The design method of the main fuel flow controller for the starting process of the APU is summarized. It’s a valuable reference for the future design of the control system of both aero-engine and auxiliary power unit.
