"Robust Output Regulation for Hybrid Systems"

The talk addresses the problem of output regulation for  linear hybrid systems.

We focus on a class of  hybrid linear SISO systems and exosystems whose dynamics have jumps according  to the value of a clock variable. The problem of designing controllers embedding an hybrid internal model of the switching exosystem in order to achieve the regulation objective is addressed, by extending key concepts and tools well-known for continuous-time systems, such as steady state, regulator equation and internal model property. Emphasis is placed on internal models and stabilizers that are robust to uncertainties entering both in the flow and jump dynamics of the hybrid controlled system. In this respect an innovative way of designing robust internal model based own the concept of invisible dynamics is presented.  The specific case of robustly tracking a spline trajectory is also presented as a relevant  applicative context.

Short Bio: Lorenzo Marconi received the M.S. degree in electrical engineering and the Ph.D. degree from the University of Bologna, Bologna, Italy, in 1995 and 1998, respectively. Since 1995, he has been with the Department of Electronics, Computer Science, and Systems at the University of Bologna where is now full professor. He has held visiting positions at various academic/research international institutions. He is coauthor of more than 200 technical publications on the subject of linear and nonlinear feedback design published on international journals, books and conference proceedings. His current research interests include nonlinear control, output regulation, control of autonomous vehicles, fault detection and isolation, fault tolerant control.

Dr. Marconi received the Outstanding Application Paper Award in 2005 from IFAC for a coauthored paper published on Automatica, and the 2014 IEEE Control Systems Magazine Outstanding Paper Award for the best paper published on the magazine in the period 2012–2013. He is IEEE fellow, a member of the IEEE Control System Society, of the Control System Society Conference Editorial Board, and the Chair of the IFAC Technical Committee on Nonlinear Control Systems.
