About the speaker

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 Polytechnic Institute of Leningrad, USSR, and the Docteur D‘Etat from the Polytechnic 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 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 Research Council (CNRS) since June 1992. Currently he is a Directeur de Recherche in the Laboratoire de Signaux et Systèmes (CentraleSupélec) in Gif-sur-Yvette, France.

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 310 scientific papers in international journals, with an h-index of 78. He has supervised 35 PhD thesis. He is a Fellow Member of the IEEE since 1999 and an IFAC Fellow since 2016. He has served as chairman in several IFAC and IEEE committees and participated in various editorial boards of international journals. Currently he is the Editor in Chief of Int. J. on Adaptive Control and Signal Processing and Editor at Large of Asian J. of Control.

Abstract

In this talk we present some new results on generation and control of oscillations in nonlinear systems and its application to nonholonomic systems. These results include the following.

  1. Orbital stabilization of nonlinear systems via the immersion and invariance technique, R. Ortega, B. Yi, J. G. Romero and A. Astolfi, Int. J. on Robust and Nonlinear Control, (arXiv:1810.00601).
  2. Orbital stabilization of nonlinear systems via energy shaping and pumping-and-damping injection, B. Yi, R. Ortega, D. Wu and W. Zhang, IEEE Conference on Decision and Control’19.
  3. Smooth, time-invariant regulation of nonholonomic systems via energy pumping-and- damping, B. Yi, R. Ortega and W. Zhang: Systems and Control Letters, (submitted), (arXiv:1712.08209.).
