Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 N° 23 (Décembre 2008) . - p. 9465–9471 Titre : Selection of controlled variables : maximum gain rule and combination of measurements Type de document : texte imprimé Auteurs : Eduardo Shigueo Hori, Auteur ; Sigurd Skogestad, Auteur Année de publication : 2009 Article en page(s) : p. 9465–9471 Note générale : Chemistry engineering Langues : Anglais (eng) Mots-clés : Selection  variables  Gain  rule  Combination  of  measurements Résumé : The appropriate selection of controlled variables is one of the most important tasks in plantwide control. In this paper, we consider the selection of secondary temperature measurements for indirect composition control of distillation columns. The maximum gain rule (maximize minimum singular value of scaled gain matrix) is compared to the exact local method, and it is found that the gain rule should be used with care for ill-conditioned plants like distillation columns. We also consider the use of optimal combinations of measurements to further reduce the effect of disturbances and implementation errors.
