Fault detection and localization applied in a fixed wing aircraft

Abstract

This paper presents the design of a system of faults detection and localization (its acronym FDI) based on a Piecewise Linear Observer implemented in F-16 fixed-wing aircraft under different regimes of flight: stable level wings, level turn, flight constant rising and roll. The scheme FDI based on observers that using to bank of linear observers for residues generation, switched by a switching law, dependent of time and the output of system. This piecewise linear state observer estimate the angular velocities of the aircraft. The dynamic model of the F-16 is considered as a set of linear models, linearized around of an operating point. The validation of the approach FDI is propose in simulation in conditions flight straight and level, which is one of the most important tasks of flying an aircraft while it is flying in the air.
