FAULT DIAGNOSIS METHOD FOR HEALTHY SENSOR OF FLY-BY-WIRE CONTROL INPUT SYSTEM

摘要

PURPOSE: A fault diagnosis system for a healthy sensor of a fly-by-wire control input system is provided to enable safe flying even in case it is unable to find a normal value due to the malfunction of a displacement sensor during aviation. CONSTITUTION: A fault diagnosis system for a healthy sensor of a fly-by-wire control input system comprises a control input apparatus and a controller. The control input apparatus includes three displacement sensors. The controller comprises a flight control module which drives an actuator(4) using a signal transmitted from the control input apparatus, a voting module which extracts the most exact signal from the signals of the three displacement sensors, a detection module which detects a normal sensor in case the voting module determines the failure of two or more sensors, and a fly control module which drives the actuator according to a control input apparatus displacement sensor signal or automatic flight control algorithm.
