Abstract
Stubborn observer redesigns were proposed in 2015 to mitigate the effect of outliers in asymptotic observers by introducing a saturation nonlinearity with adaptive thresholds on the output injection term. With impulsive disturbances, or outliers, saturation trims away part of the perturbation in the continuous-time setting, while preserving the asymptotic convergence properties of the original observer: a fact that we illustrate in the first part of this talk. In a second part of the talk, we discuss recent discrete-time results where finite-memory buffers allow obtaining complete rejection under an appropriate dwell-time condition on the outliers occurrence. Most of the talk will focus on a nonlinear setting, but relevant linear scenarios will be discussed as applications.
Biography
Luca Zaccarian received the Laurea and the Ph.D. degrees from the University of Roma Tor Vergata (Italy) in 1995 and 2000, respectively. He was Assistant Professor in control engineering at the University of Roma, Tor Vergata (Italy), from 2000 to 2006 and then Associate Professor. Since 2011 he is Directeur de Recherche at the LAAS-CNRS, Toulouse (France) and since 2013 he holds a part-time professor position at the University of Trento, Italy. Luca Zaccarian’s main research interests include analysis and design of nonlinear and hybrid control systems, modeling and control of mechatronic systems. He has served in the organizing committee and TPC of several IEEE and IFAC conferences. He has been a member of the IEEE-CSS Conference Editorial Board and an associate editor for Systems and Control Letters and IEEE Transactions on Automatic Control. He is currently senior editor for nonlinear systems and control and deputy editor-in-chief for the IFAC journal Automatica, a member of the EUCA-CEB and an associate editor for the European Journal of Control. He served in the IEEE-CSS Board of Governors in 2014 (nominated member), and 2017-2019 (elected member). He has been nominated Director of Operations in the IEEE-CSS Executive Committee for the triennium 2027-2029. He was a recipient of the 2001 O. Hugo Schuck Best Paper Award given by the American Automatic Control Council. He is a fellow of the IEEE, class of 2016.
