This paper presents a software-based approach to the problem of distributed actuator failure diagnosis under resource and deadline constraints in fly-by-wire systems using comparison of actuator behaviour and corresponding mathematical model. (2k + 1) replicated control and diagnosis tasks are executed to tolerate k-faults in the control and diagnosis functions. The proposed method has been evaluated through simulation based on real data and has been compared with a single rate steer-by-wire (SBW) systems recently suggested by Kandasamy et al. [1].
