New Results on Identification and Adaptive Control

Back
Abstract:
In this talk we review some recent results on adaptive (and pseudo-adaptive) control reported in the literature. This results include the following.
(i) A contraction approach to immersion and invariance (I&I) adaptive control of nonlinearly parameterized, nonlinear (NLPNL) systems.
(ii) Pseudo-adaptive I&I stabilization of NLPNL systems with fast time-varying parameters
(iii) Facts about L1-Pseudo-adaptive control

Biographical Sketch:
Romeo Ortega was born in Mexico. He obtained his BSc in Electrical and Mechanical Engineering from the National University of Mexico, Master of Engineering from Polytechnical Institute of Leningrad, USSR, and the Docteur D`Etat from the Politechnical Institute of Grenoble, France in 1974, 1978 and 1984 respectively. He then joined the National University of Mexico, where he worked until 1989. He was a Visiting Professor at the University of Illinois in 1987-88 and at the McGill University in 1991-1992, and a Fellow of the Japan Society for Promotion of Science in 1990-1991. He has been a member of the French National Researcher Council (CNRS) since June 1992. Currently he is a Directeur de Recherche, 1eme classe, in the Laboratoire de Signaux et Systemes (SUPELEC) in Paris. His research interests are in the fields of nonlinear and adaptive control, with special emphasis on applications.

Dr Ortega has published three books and more than 250 scientific papers in international journals, with an h-index of 66. He has supervised more than 30 PhD thesis. He is a Fellow Member of the IEEE since 1999. He has served as chairman in several IFAC and IEEE committees and participated in various editorial boards of international journals.
