Research output: Contribution to journalArticlepeer-review


In this paper a fault detection and isolation method (FDI) for an Unmanned Aerial Vehicle (UAV) is presented. The proposed method deals with control surface failures while the aircraft is equipped with an autopilot. This method does not require the complete model of the system. Fault detection consists of exciting judiciously actuators and analyzing cross- correlations between measurements. The temporal and frequential properties of the signal are analyzed during transient of the failure. From this point of view, a wavelet analysis has been implemented to isolate the faulty control surfaces.
