Realizing fault-tolerant asynchronous sequential machines using corrective control / Jung-Min Yang in IEEE Transactions on control systems technology, Vol. 18 N° 6 (Novembre 2010) 

Public ISBD [article]  in IEEE Transactions on control systems technology > Vol. 18 N° 6 (Novembre 2010) . - pp. 1457-1463 Titre : Realizing fault-tolerant asynchronous sequential machines using corrective control Type de document : texte imprimé Auteurs : Jung-Min Yang, Auteur ; Seong Woo Kwak, Auteur Année de publication : 2011 Article en page(s) : pp. 1457-1463 Note générale : Génie Aérospatial Langues : Anglais (eng) Mots-clés : Asynchronous  sequential  machines  Corrective  control  State  fault  tolerance  Triple  modular  redundancy  (TMR) Index. décimale : 629.1 Résumé : A control scheme is presented for realizing state fault-tolerance of asynchronous sequential machines. An unobservable disturbance input can infiltrate into asynchronous machines and provoke unauthorized state transitions. The objective is to propose automatic state feedback controllers that detect penetration of the disturbance input and counteract state faults so as to return the controlled machine to its original state. A necessary and sufficient condition for the existence of such a controller is presented in a theoretical framework and an architecture of asynchronous triple modular redundancy is addressed as a case study.
