Abstract:

In view of the demand for future aero-engines,combined with the characteristics and advantages of multi electric distributed control,the key technologies of fault diagnosis and accommodation of multi-electric distributed engine control system are studied based on advanced algorithms. Firstly,this paper summarizes the fault diagnosis and accommodation technology of multi-electric distributed engine control system at home and abroad from four aspects:distributed engine control system,more electric engine,fault diagnosis and fault-tolerant control methods and hardware in the loop simulation platform,and points out the key problems of fault diagnosis and accommodation of multi-electric distributed engine control system at present. Then the key technologies are proposed,which are the design of fault diagnosis and accommodation architecture of multi-electric distributed engine control system,the model-based fault diagnosis and fault-tolerant control method,the fault diagnosis and accommodation scheme of dual active redundant motor control system,the electro-mechanical actuator fault diagnosis and accommodation scheme based on deep learning,and the construction of hardware in the loop simulation platform. Finally,the future development trend of fault diagnosis and fault tolerance of aeroengine multi electric distributed control system is prospected.

Key words: aero-engine, multi-electric distributed engine control system, fault diagnosis and accommodation, fault-tolerant control, hardware-in-the-loop
