"Switched systems and control over graphs"
Abstract:We
present recent developments in our effort to provide systematic
analysis tools for control design of distributed systems which may
operate over wireline or wireless networks. New results and current
work are presented on the control of distributed systems formed from
the interconnection of multiple heterogeneous input-output subsystems.
In particular we will discuss progress on two specific problems. The
first is control design over graph interconnections, and is aimed at
addressing the need for synthesizing controllers that have a specific
communication topology. The second problem is that of designing systems
where information is received with varying latency; our approach is by
means of our recent and more general work on switched and Markovian
linear systems.
Our new multi-vehicles testbed (HOTDEC) designed for extensive
experimentation with the control issues arising from control over
networks will also be briefly presented. It consists of autonomous
hovercraft, wirelessly communicating with each other and users on the
Internet.
Biography:Geir E. Dullerud is Professor of Mechanical Engineering, and Research Professor of the Coordinated Science Laboratory, at the University of Illinois at Urbana-Champaign. Prior to this he was on faculty in Applied Mathematics at the University of Waterloo 1996-1998, after being a Research Fellow at the California Institute of Technology from 1994-1995, in the Control and Dynamical Systems Department. In 1994 he received his PhD from the University of Cambridge, England. He has published two books: "A Course in Robust Control Theory" (with F. Paganini), Texts in Applied Mathematics, Springer, 2000, and "Control of Uncertain Sampled-data Systems", Birkhauser 1996. His areas of current research interest include networked and cooperative control, robotic vehicles, complex and hybrid dynamical systems. In 1999 he received the CAREER Award from the National Science Foundation, and in 2005 the Xerox Faculty Research Award at UIUC. During the academic year 2005-2006 he held a visiting faculty position in the Aeronautics and Astronautics Department at Stanford University.
