Reduction in the number of gain-scheduling parameters using dimensional transformation / Haftay Hailu in Transactions of the ASME . Journal of dynamic systems, measurement, and control, Vol. 130 N° 3 (Mai/Juin 2008) 

Public ISBD [article]  in Transactions of the ASME . Journal of dynamic systems, measurement, and control > Vol. 130 N° 3 (Mai/Juin 2008) . - 06 p. Titre : Reduction in the number of gain-scheduling parameters using dimensional transformation Type de document : texte imprimé Auteurs : Haftay Hailu, Auteur ; Sean Brennan, Auteur Année de publication : 2010 Article en page(s) : 06 p. Note générale : dynamic systems Langues : Anglais (eng) Mots-clés : gain-scheduled  controller;  linear  parameter-varying  system;  dimensional  transformation;  matrix-based  approach Résumé : A method is presented that can often reduce the number of scheduling parameters for gain-scheduled controller implementation by transformation of the system representation using parameter-dependent dimensional transformations. In some cases, the reduction in parameter dependence is so significant that a linear parameter-varying system can be transformed to an equivalent linear time invariant (LTI) system, and a simple example of this is given. A general analysis of the parameter-dependent dimensional transformation using a matrix-based approach is then presented. It is shown that, while some transformations simplify gain scheduling, others may increase the number of scheduling parameters. This work explores the mathematical conditions causing an increase or decrease in varying parameters resulting from a given transformation, thereby allowing one to seek transformations that most reduce the number of gain-scheduled parameters in the controller synthesis step.
