Observer−Controller Design for a Class of Stable/Unstable Inverse Response Processes / Carles Pedret in Industrial & engineering chemistry research, Vol. 48 N° 24 (Décembre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 24 (Décembre 2009) . - pp. 10986–10993 Titre : Observer−Controller Design for a Class of Stable/Unstable Inverse Response Processes Type de document : texte imprimé Auteurs : Carles Pedret, Auteur ; Salva Alcántara, Auteur ; Ramon Vilanova, Auteur Année de publication : 2010 Article en page(s) : pp. 10986–10993 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Observer−Controller--Design--Class--Stable--Unstable--Inverse--Response--Processes Résumé : This paper proposes the use of a two-degree-of-freedom configuration aimed at the control of inverse response processes. An observer−controller scheme based on coprime factorization results in a Smith-type predictor well suited for both stable and unstable inverse response processes. The design procedure is carried in two steps. First, the controller is designed providing an adjustable parameter to cope with the reference input tracking. Second, the observer blocks are selected for closed-loop properties, offering another tuning parameter to compromise between robust stability and disturbance rejection performance. As a result, the nominal set point response is decoupled from the disturbance response. To show the applicability of the proposed control configuration, its performance is compared by simulation with different approaches.
