Arun Srikanth, Auteur ; J. V. N. Sreeram, Auteur Année de publication : 2012 Article en page(s) : pp. 13045-13055 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : System identification Design Résumé : The primary objective in solving optimal input design problems is to obtain maximally informative inputs to be used as perturbation signals in system identification experiments. In plant-fiiendly identification, the designer has to respect constraints on experiment time, input and output amplitudes or input move sizes. This work focuses on plant friendly input design with constraints on input move size and output power. We present a convex relaxation to the problem of designing an informative input subject to input move size and output power constraints. The problem is finitely parametrized using ideas from Tchebycheff systems and reformulated as a SemiDefinite Progamme.
