Titre : Recursive identification in transmittance of under‐operated mechanical system (applied to inversed pendulum) Auteurs : Jacques Kadima Kazaku, Revue : Control Numéro : Issue 1 Volume : 1 Date : 2018/01/8 DOI : 10.21494/ISTE.OP.2018.0278 ISSN : 2631-4924 Résumé : A new approach of identifying mechanical system under-operated is presented in this article. The basic idea is to spread the extensive least-square algorithm and the Stieglitz and McBride algorithm to the case of under-operated systems. The considered models are OE and ARMAX type. The comparative evaluation through simulation using numerical example shows clearly the quality of the identification using this approach compared to the result obtained by the non-recursive linear least-squared methods. The use of the OE and ARMAX models has made the improvement of the asymptotic convergence of these algorithms possible. Éditeur : ISTE OpenScience
