Redundancy design and research of safety fly-by-wire flight control system

In order to improve the safety of fly-by-wire flight control system and meet the airworthiness requirements, this paper takes the fly-by-wire flight control system of a manned airship as an example, and proposes a dual-redundancy flight control computer. The redundant architecture is designed based on redundancy technology and combined with an effective redundancy management algorithm, so that the fly-by-wire flight control computer can detect and isolate faults quickly and accurately. The results show that the flight control computer scheme has clear structure, reasonable redundancy design and implementation, improves the safety and reliability of fly-by-wire flight control system, meets the technical requirements of a manned airship, and can be used as a reference scheme for the design of high safety and high reliability unmanned airship.
