Control of Networked and Distributed Heterogeneous Systems

Professor Geir E. Dullerud

University of Illinois – Urbana

Department of Mechanical and Industrial Engineering

Abstract:

We present recent developments in our effort to provide systematic strategies 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. Part of the talk will focus on such linear systems that do not possess the usual shift invariance property with respect to temporal or spatial variables. The work is developed in an operator theoretic setting, and makes use of semidefinite programming as a central tool. Pertaining to modeling and analyzing network delays the seminar will include recent work on Markovian jump linear systems.

Our new multi-vehicles testbed (HOTDEC) designed for extensive experimentation with the control issues arising from control over networks will also be presented. It consists of autonomous hovercraft, wirelessly communicating with each other and users on the Internet.

BIO:

Geir E. Dullerud is Associate Professor of Mechanical Engineering, and Research Associate Professor of the Coordinated Science Laboratory, at the University of Illinois at Urbana-Champaign. Prior to this he was Assistant Professor of Applied Mathematics at the University of Waterloo 1996-1998, after being a Research Fellow at the California Institute of Technology from 1994-1995. 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.
