Fault-tolerant Control for Dual-redundant Aircraft Power System Controller

This article detailed introduce the fighter jet power supply controller with Twin-engines design and implementation.Aircraft power supply controller is an aircraft avionics system which be used for management the aircraft power supply system,is the core equipment of aircraft power supply system,take the mission of aircraft safety.In order to improve the power controller of aircraft reliability and flexibility,this article abandoned the traditional approach which is to using of simulation technology to design the power supply controller,but using the advanced digital technology to achieving the management to aircraft power supply system and power distribution system,used active replication fault-tolerant technology to design aircraft digital power controller,designed the dual redundant aircraft power supply controller.In the event of channel error case,the whole system work correctly.In this paper,the aircraft power supply system controller fault tolerance were studied,including dual redundant system management strategy,synchronization control mechanism,redundancy management and fault synthesis,the signal is monitored and channel switching logic.
