Referat plenarny "Diagnosability of hybrid dynamical systems" wygłosiła profesor Maria Domenica Di Benedetto, University of L’Aquila, Italy
Hybrid systems, i.e., heterogeneous systems that include discrete and continuous-time subsystems, have been used to model control applications e.g. in automotive control, air traffic management systems, smart grids and intelligent manufacturing. Failure in this kind of applications can cause irreparable damage to the physical controlled systems and to the people who depend on it, or may cause large direct and indirect economic losses. Therefore, security for hybrid systems represent a significant concern. In this respect, observability and diagnosability play an important role since they are essential in characterizing the possibility of identifying the system’s hybrid state, and in particular, the occurrence of specific states that may correspond to malfunctioning due to a fault or an adversarial attack. In this talk, I review and place in context how the continuous and the discrete dynamics, as well as their interactions, intervene in the observability and diagnosability properties of a general class of hybrid systems. I also illustrate under which conditions the hybrid system’s state can be correctly estimated even when the system is under attack. An example related to network topology changes due to faults or attacks will illustrate the results.

Maria Domenica Di Benedetto is a Professor of Automatic Control at University of L’Aquila (Italy). She received her Master degree in Electrical Engineering and Computer Science from University of Roma "La Sapienza" and holds the PhD degree (“Docteur-Ingenieur” Spécialité Automatique et Traitement du Signal) and the degree “Doctorat d'Etat ès Sciences” (Spécialité Sciences Physiques), both from Université de Paris-Sud (Orsay, France). She has been Adjunct Professor from 1995 to 2002, and McKay Professor from 1990 to 1995, at the Department of EECS of the University of California at Berkeley. She held visiting positions at MIT, at the University of Michigan Ann Arbor, and at the Ecole Nationale Supérieure de Mécanique in Nantes (France). Her research interests are in the areas of nonlinear and hybrid systems control theory, diagnosability and predictability in cyber-physical systems, and applications to traffic control, smart grids and biological systems.
From 2001 to 2019, Prof. Di Benedetto has been the Director of the Italian Center of Excellence for Research DEWS "Architectures and Design methodologies for Embedded controllers, Wireless interconnect and System-on-Chip" established at the University of L’Aquila in 2001. She has been the President of the Italian Association of Researchers in Automatic Control (SIDRA) from 2013 to 2019. She is the President of the European Embedded Control Institute since 2009.
Dr. Di Benedetto is a Fellow of the IEEE and IFAC. She has been a member of the IEEE Control Systems Technical Fields Award Committee, Chair of the Standing Committee on Fellow Nominations of the IEEE CSS, member of the IEEE Fellow Evaluation Committee of the IEEE CSS. She is the IFAC Chair of the Nathaniel B. Nichols Medal Selection Committee for the 2020-2023 triennium. She is currently a Distinguished Lecturer of the IEEE CSS and is serving as the VP for Membership Activities (2020-21) in the Executive Committee of the IEEE CSS. She is Editor of the IEEE Press Book Series in Control Systems Theory and Applications.
