Output Regulation of Multivariable Nonlinear Systems Using Outputs not vanishing in Steady State

Date : 19/01/2022 De 16h00 A 17h00

Lorenzo Marconi, University of Bologna, Italy

The presentation deals with the problem of output regulation for linear and nonlinear systems. After a short introduction about the theoretical foundations of output regulation and the relevance of internal model-based regulators, the talk will deal with the design of the regulator in the cases in which, besides the regulation error, others measurements not necessarily zero in steady state are available. Motivated by a linear analysis that is overviewed in the initial part of the talk, we propose a control structure in which the extra measurements are filtered by a post-processor specifically designed to block their steady state value. The method proposed in the presentation lends itself to address relevant cases of nonlinear systems that are nonminimum-phase between the control input and the regulation error and for which extra measurements are necessary, or simply desirable, to succeed in robust output feedback stabilisation.

Lorenzo Marconi graduated in 1995 in Electrical Engineering from the University of Bologna. Since 1995 he has been with the Department of Electronics, Computer Science and Systems at University of Bologna, where he obtained his Ph.D. degree in March 1998. From 1999 he has been an Assistant Professor in the same Department where is now Full Professor since January 2016.
He has held visiting positions at and collaborations with various academic/research international institutions. He is co-author of more than 250 technical publications on the subject of linear and nonlinear feedback design published on international journals, books and conference proceedings. He is also co-author of three international monographs.
In 2005, he has been awarded jointly by Elsevier and the International Federation of Automatic Control (IFAC) for the best paper published in the period 2002-2005 on “Automatica”. He is also the recipient of the 2014 IEEE Control Systems Magazine Outstanding Paper Award for the best paper published on the magazine in the period 2012-2013, He is the recipient of the 2018 O. Hugo Schuck Best Paper Award assigned by the American Automatic Control Council for the best paper presented at the 2017 American Control Conference. He is Fellow of IEEE for “contributions to feedback design of nonlinear systems and unmanned aerial vehicles”
He chaired the IFAC Technical Committee on ``Nonlinear Control Systems" from 2011 to 2017 and he is member of the IEEE Technical committee on ``Nonlinear Systems''. Dr. Marconi has been the chair of the International Program Committee of the 8th IFAC Workshop on nonlinear control systems (NOLCOS) held at University of Bologna on September 2010. He is the Principal Investigator of the EU projects AiRobots (2010-2013), SHERPA (2013-2017), AirBorne (2018-).
He is now serving as Senior Editor of IEEE Transaction on Automatic Control (Associate Editor from 2009 to 2013).
His current research interests include nonlinear control, output regulation and stabilisation of nonlinear systems, control of autonomous aerial vehicles, robust control, fault detection and isolation, fault tolerant control.
