SMAC-FDI: A single model active fault detection and isolation system for unmanned aircraft

Ducard G. J. J.

International Journal of Applied Mathematics and Computer Science

2015

Vol. 25, no. 1

189--201

This article presents a single model active fault detection and isolation system (SMAC-FDI) which is designed to efficiently detect and isolate a faulty actuator in a system, such as a small (unmanned) aircraft. This FDI system is based on a single and simple aerodynamic model of an aircraft in order to generate some residuals, as soon as an actuator fault occurs. These residuals are used to trigger an active strategy based on artificial exciting signals that searches within the residuals for the signature of an actuator fault. Fault isolation is carried out through an innovative mechanism that does not use the previous residuals but the actuator control signals directly. In addition, the paper presents a complete parameter-tuning strategy for this FDI system. The novel concepts are backed-up by simulations of a small unmanned aircraft experiencing successive actuator failures. The robustness of the SMAC-FDI method is tested in the presence of model uncertainties, realistic sensor noise and wind gusts. Finally, the paper concludes with a discussion on the computational efficiency of the method and its ability to run on small microcontrollers.

W artykule przedstawiono wybrane obiekty latające różnych producentów oraz dokonano analizy praktycznego ich zastosowania w dziedzinie cywilnej i wojskowej. Powszechnie wiadomo, że bezzałogowe samoloty używane są w wojsku do obserwacji i atakowania wybranych celów. W artykule przedstawiono najbardziej nietypowe rozwiązania konstrukcyjne stosowane nie tylko w wojsku.

The unmanned aerial vehicles (UAV) from different manufacturers were presented in the paper and the possibilities of their military and civilian applications were studied. It is widely known that UAV in military applications are used to monitor and attack selected targets. In the paper the most untypical constructions used not only in the army were presented.
