Description
technical field [0001] The invention relates to the control system test technology of an aero-engine, in particular to a semi-physical simulation rapid configuration system for control system test. Background technique [0002] Modern mainstream commercial aero engines all adopt the FADEC (Full Authority Digital Electronics Control) system, that is, through the electronic controller, the control function of the engine body and the task of cooperating with the aircraft are completed with full authority within the full envelope of the aircraft. [0003] The engine control system is mainly composed of electronic controllers, engine monitoring devices, fuel components, actuating components, FADEC alternators, sensors and cables, etc. It is a complex control system with high reliability and high safety. [0004] Most of the control system tests of aero-engines at home and abroad use semi-physical simulation systems to iteratively test the robustness, fault tolerance, and complian...
