Robust fault diagnosis based on nonlinear model of hydraulic gauge control system on rolling mill / Min Dong in IEEE Transactions on control systems technology, Vol. 18 N° 2 (Mars 2010) 

Public ISBD [article]  in IEEE Transactions on control systems technology > Vol. 18 N° 2 (Mars 2010) . - pp. 510-515 Titre : Robust fault diagnosis based on nonlinear model of hydraulic gauge control system on rolling mill Type de document : texte imprimé Auteurs : Min Dong, Auteur ; Cai Liu, Auteur ; Guoyou Li, Auteur Année de publication : 2011 Article en page(s) : pp. 510-515 Note générale : Génie Aérospatial Langues : Anglais (eng) Mots-clés : Automatic  gauge  control  (AGC)  Decoupling  Differentail  geometric  method  Mathematical  model  Nonlinear  observer Index. décimale : 629.1 Résumé : A nonlinear model of a hydraulic automatic gauge control (AGC) system is established for fault detection and isolation (FDI). By analyzing the relationship between faults and load uncertainties, a decoupling subsystem has been derived using a differential geometric approach. An exponential gain observer has been designed based on the observable decoupling subsystem. Diagnosis residual signal is sensitive to designated faults and robust to load uncertainty. Two real data examples verify that the observer is stable and asymptotically convergent. The correctness and superiority are testified by actual data examples.
