Fly-by-light Flight Control System Technology Research for UAV

In order to examine the feasibility of fly-by-light(FBL)control system, a dual-redundancy UAV FBL control system based on IEEE-1394B was designed and implemented, on which the study and design of system architecture, detail design of its components, as well as ground integration testing and analysis were achieved. Implementation and verification were conducted for several key techniques such as distributed FBL system architecture, high speed optic bus and optic displacement sensor etc. Experiments demonstrate that the functions and performance of the FBL control system reaches the design requirements of fly-by-wire control systems. Study results enhance technology readiness of FBL system and also lay a foundation for its future engineering application.
