Trends in distributed control for constrained systems

Back
Abstract:
In the recent years, man-made systems characterized by a large number of states or deployed over a wide area have triggered a renowned interest in methods for distributing the structure of controllers. While these problems have been thoroughly studied since the 70's for unconstrained systems, much less mature are methods for distributing Model Predictive Control (MPC) that is the standard for the regulation of constrained systems. Current research in distributed MPC tries to conciliate conflicting objectives such as weakening assumptions on system structure and constraints, minimizing real-time transmission of information among controllers and maximizing the operational range of the closed-loop system. In this talk we will illustrate a new distributed MPC scheme trying to fulfill most of these requirements. We will also consider decentralization of the control design process, that is desirable for easing revamping of control systems or addition/removal of subsystems. We will then present a "plug-and-play" decentralized MPC method where the design of a controller for a subsystem involves only knowledge of subsystems physically coupled to it. Applications to the design of automatic generation control layers for frequency control in power networks will be discussed.

Biographical Sketch:
Giancarlo Ferrari Trecate obtained the "Laurea" degree in Computer Engineering in 1995 and the Ph.D. degree in Electronic and Computer Engineering in 1999, both from the University of Pavia. In fall 1998 he joined the Automatic Control Laboratory at ETH (Zurich, Switzerland) as a Postdoctoral fellow. In 1999 he won the grant ``assegno di ricerca'' at the University of Pavia and in 2000 he was appointed Oberassistent at ETH. In January 2002 he moved to INRIA (Rocquencourt, France) as a Research Fellow. In March 2005, he was awarded a Researchers Mobility Fellowship (aka "Rientro dei Cervelli") from the Italian Ministry of University and Research for joining the Dipartimento di Elettronica ed Informazione of the Politecnico di Milano where he stayed until October 2005. From November 2005 he is associate professor at DIS, Università degli Studi di Pavia.

Giancarlo Ferrari Trecate has been member of the IFAC Technical Committee on Power Plants and Power Systems and he is member of the IFAC Technical Committee on Control Design where he has been responsible of the working group on Systems and Synthetic Biology. From January 2009 he is member of the Technical Committee on Systems Biology of the IEEE Systems, Man, and Cybernetics Society. From 2007 he is member of the Conference Editorial Board of the IEEE Control Systems Society. From 2010 he is an associate editor of Automatica. His research interests include distributed control and state estimation, control of multi-agent systems, modeling and analysis of biochemical networks, hybrid systems and Bayesian learning.
