The aeroengine control system is a safety-critical system for aeroengine， crucial for generating reliable thrust or power within the entire flight envelope of the engine. This paper presents the evolution of the aeroengine control system， summarizes and analyzes the development of three key system-level technologies， including architecture design， control law design， and fault diagnosis and condition monitoring design， as well as simulation enabling technologies. The discussion on the applicability of these technologies in engineering is then conducted. The prospects for future development directions and key research areas are finally explored， providing a valuable reference for the design of next generation aeroengine control systems.
