Comparative analysis of some approaches to the autotuning of cascade controls / Alberto Leva in Industrial & engineering chemistry research, Vol. 48 N° 12 (Juin 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 12 (Juin 2009) . - pp. 5708–5718 Titre : Comparative analysis of some approaches to the autotuning of cascade controls Type de document : texte imprimé Auteurs : Alberto Leva, Auteur ; Alberto Marinelli, Auteur Année de publication : 2009 Article en page(s) : pp. 5708–5718 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Cascade  controls  Autotuning Résumé : Some approaches to the autotuning of cascade controls are comparatively analyzed on the basis of a conveniently characterized test batch. The reported analysis results provide some remarks and possible guidelines for the design of cascade autotuners. Peculiar to the presented simulation study is that the “identification experiment” is considered as an integral part of the autotuning procedure—an aspect of the overall matter that is seldom addressed in the literature.

Extending ideal PID tuning rules to the ISA real structure / Martina Maggio in Industrial & engineering chemistry research, Vol. 50 N° 16 (Août 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 16 (Août 2011) . - pp. 9657-9666 Titre : Extending ideal PID tuning rules to the ISA real structure : two procedures and a benchmark campaign Type de document : texte imprimé Auteurs : Martina Maggio, Auteur ; Alberto Leva, Auteur Année de publication : 2011 Article en page(s) : pp. 9657-9666 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Benchmarks Résumé : Although virtually any installed PID controller encompasses a derivative filter, and very frequently takes the standard ISA form, many tuning rules refer to the ideal controller structure, which is subsequently made realizable by introducing the so-called "derivative filter" a posteriori. Doing so can sometimes lead to undesired results. This paper investigates the matter and discusses two very simple but rigorous procedures to extend ideal PID tuning rules to the ISA controller. A benchmark simulation campaign, referring to several well-assessed rules, demonstrates the opportunity and efficacy of the proposed extensions. A quite realistic test referring to a typical process control case is also presented.
