The complexity of systems in modern engineering is steadily increasing and this has triggered a growing interest in the control of large interconnections of subsystems. In the past, several contributions addressed the problem of parallelizing on-line computation of control actions using local regulators arranged in decentralized or distributed architectures.
In this talk, instead, we will address scalability at the control design level and discuss constraints of the information flow that make the complexity of synthesizing a local controller independent of the total number of subsystems. Scalability of design is central in cyber-physical systems, where subsystems enter and leave over time, as well as for the replacement of sensors and actuators with minimal human intervention. Along this direction, we will present approaches to the plug-and-play design of local controllers enabling seamless addition and removal of subsystems. The first part of the talk will focus on systems with physical bounds on inputs and states.
Then we will discuss plug-and-play design for unconstrained systems based on the concept of neutral interactions, along with its application to voltage and frequency control in islanded microgrids. Simulation and experimental results confirm the effectiveness of plug-and-play controllers in handling the addition and removal of generation units while preserving overall voltage stability. The final part of the talk will be devoted to research perspectives for enhancing security and autonomy of large-scale control systems.
Bio: Giancarlo Ferrari-Trecate received the M.Sc. degree in Computer Engineering and the Ph.D. degree in Electronic and Computer Engineering from the of the Università degli Studi di Pavia, Italy, in 1995 and 1999. Since November 2005, he is an Associate Professor at the Dipartimento di Ingegneria Industriale e dell'Informazione of the Università degli Studi di Pavia. In spring 1998, he was a Visiting Researcher at the Neural Computing Research Group, University of Birmingham, U.K. In fall 1998, he joined the Automatic Control Laboratory, ETH, Zurich, Switzerland, as a Postdoctoral Fellow. He was appointed Oberassistent at ETH, in 2000. In 2002, he joined INRIA, Rocquencourt, France, as a Research Fellow. From March to October 2005, he worked at the Politecnico di Milano, Italy.
His research interests include distributed and scalable control, control of microgrids, modeling and analysis of biochemical networks, hybrid systems and Bayesian learning.
Giancarlo Ferrari-Trecate received the "assegno di ricerca" Grant from the University of Pavia in 1999 and the Researcher Mobility Grant from the Italian Ministry of Education, University and Research in 2005.
