Abstract:
A fly-by-wire flight backup control system and method. The fly-by-wire flight backup control system may comprise a backup sensor module (120) and a backup control computer (130), which is coupled to the backup sensor module (120), wherein the backup control computer (130) receives a state signal of a main control channel (101); the main control channel (101) generates a control command on the basis of a sensor signal from a main control sensor module (112), so as to control a main control servo actuation module (114); and when the state signal of the main control channel (101) that is received by the backup control computer (130) indicates that the main control channel (101) fails, the backup control computer (130) supplies power to the backup sensor module (120) and a backup servo actuation module (140), and generates a control command on the basis of a sensor signal received from the backup sensor module (120), so as to control the backup servo actuation module (140).
