Decomposability of the control structure design problem of recycle systems / Marcell Horvath in Industrial & engineering chemistry research, Vol. 48 N° 13 (Juillet 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 13 (Juillet 2009) . - pp. 6339–6345 Titre : Decomposability of the control structure design problem of recycle systems Type de document : texte imprimé Auteurs : Marcell Horvath, Auteur ; Péter Mizsey, Auteur Année de publication : 2009 Article en page(s) : pp. 6339–6345 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Control  structure  design  Whole  process  simultaneously Résumé : The control structure design is an important part of process synthesis tasks. The design becomes more difficult if recycle is present in the process to be controlled. The objective of this work is to clear up if the control structure design should be completed for the whole process simultaneously or it can be decomposed into subproblems involving only one unit of the whole system. Investigations show that the recycle can have an effect on the control structure that complicates the design problem. Simple case studies and exhaustive investigation of the industrial control problem are completed. Our investigations prove that decomposability can be applied simplifying the proper pairing of the controlled and manipulated variables, and this can facilitate the control structure design problem.
