Fault detection for a class of uncertain state-feedback control systems / Yang, Guang-Hong in IEEE Transactions on control systems technology, Vol. 18 N° 1 (Janvier 2010) 

Public ISBD [article]  in IEEE Transactions on control systems technology > Vol. 18 N° 1 (Janvier 2010) . - pp. 201-212 Titre : Fault detection for a class of uncertain state-feedback control systems Type de document : texte imprimé Auteurs : Yang, Guang-Hong, Auteur ; Heng Wang, Auteur Année de publication : 2011 Article en page(s) : pp. 201-212 Note générale : Génie Aérospatial Langues : Anglais (eng) Mots-clés : Fault  detection  Linear  martrix  inequality  (LMI)  Linear  systems  State  feedback  Tracking Index. décimale : 629.1 Résumé : This brief studies the problem of fault detection for a class of uncertain state-feedback tracking control systems with constant reference inputs and bounded disturbances. The considered systems are modeled via multiple modes, namely, fault-free case and faulty cases. Actuator stuck faults, including outage cases, are considered. With the aid of the finite-frequency positive-realness approach, a new linear-matrix-inequality-based fault detection method for control systems is obtained and applied to fault detection for flight control systems. An F-18 aircraft model is included in the simulation to illustrate the effectiveness of the proposed method.
