Design of reactor–separator–recycle systems based on the optimization of estimations of the domain of attraction / Luis G. Matallana in Industrial & engineering chemistry research, Vol. 50 N° 11 (Juin 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 11 (Juin 2011) Titre : Design of reactor–separator–recycle systems based on the optimization of estimations of the domain of attraction Type de document : texte imprimé Auteurs : Luis G. Matallana, Auteur ; Anibal M. Blanco, Auteur ; J. Alberto Bandoni, Auteur Année de publication : 2011 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Reactor  separator  recycle  Estimations  attraction Résumé : In this paper, an optimization-based methodology is applied to the design of a reactor–separator–recycle system based on a measure of the extension of the domain of attraction of the operating equilibrium. The approach consists in maximizing the radius of a ball in the state space contained in the region of negative definiteness of the time derivative of a quadratic Lyapunov function. A two-level optimization strategy is proposed that solves a deterministic nonconvex global optimization problem at the inner level. To cope with the non-differentiability introduced by the inner problem, we applied a stochastic algorithm to manipulate the design variables at the outer level.
