Abstract: Redundancy technology is a key means of improving the reliability and security of flybywire (FBW) systems. This thesis focused on the key technology which was synchronization, cross channel data link (CCDL) and vote & monitor of the signal in quadrupleredundancy servo actuator system to research and design. It is better to achieve the redundancy management tasks and servo control of the servo system, and improve the reliability and the faulttolerant ability of the system. The quadruple redundancy can also achieve once/twice failuresoperation and thrice failuressafety.
Key words: quadrupleredundancy; synchronization; cross channel data link; redundancy management
