On the integrity of uncertain systems with structured uncertainty / Majid Firouzbahrami in Industrial & engineering chemistry research, Vol. 50 N° 24 (Décembre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 24 (Décembre 2011) . - pp. 13940-13946 Titre : On the integrity of uncertain systems with structured uncertainty Type de document : texte imprimé Auteurs : Majid Firouzbahrami, Auteur ; Amin Nobakhti, Auteur Année de publication : 2012 Article en page(s) : pp. 13940-13946 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Uncertainty  Uncertain  system Résumé : The integity of decentralized controllers with integral action, with respect to loop failures, has been researched relatively well. Important results have been found, with respect to the Relative Gain Array (RGA). However, less has been done on the treatment of the integrity of uncertain systems. This paper builds on the more-recent progress on the analysis of uncertain systems and presents new conditions for the integrity of closed-loop systems. The developed Integral Controllable (IC), Integal Controllable with Integrity (ICI), and Decentralized Integral Controllability (DIC) conditions are derived using a model of uncertainties that allows both unstructured and structured independent uncertainties to be studied. A convex framework for the evaluation of the conditions is also presented. The utility of the conditions are illustrated through application to existing examples from the literature.
