Abstract
Distributed control systems have sustained tremendous growth rates recently due to the proliferation of digital and networking technologies, and include a variety of sensor/actuator networks, such as electric power distribution systems (e.g., smart grids), robotic networks, and transportation systems of various sorts. We consider a distributed system whose components posses some initial values and can exchange locally information in an iterative fashion via interconnections that form an arbitrary, possibly directed topology. We focus on developing distributed strategies for computing functions (such as the average) of the initial values of the components using linear iterative updates in which the nodes maintain and update their values based on linear combinations of their own values and the values they successfully receive from their neighbors. We describe strategies for the nodes to asymptotically reach consensus to the average of these initial values, by appropriately adapting—in a distributed manner—the weights used in these linear updates.
Biography
Christoforos Hadjicostis is Professor of Electrical and Computer Engineering at the University of Cyprus. He received S.B. degrees, the M.Eng. degree, and the Ph.D. degree in Electrical Engineering and Computer Science, all from MIT. From 1999 to 2007, he was Assistant and then Associate Professor with the Department of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign. Since 2007, he has been with the Department of Electrical and Computer Engineering at the University of Cyprus. His research focuses on fault diagnosis and tolerance in distributed dynamic systems; error control coding; monitoring, diagnosis and control of large-scale discrete event systems; and related applications in embedded systems, distributed robotics, anomaly detection and network security, and biomolecular networks. He is the author of a research monograph on “Coding Approaches to Fault Tolerance in Combinational and Dynamic Systems” (Springer, 978-0-7923-7624-8) and the recipient of several awards, including a 2001 NSF Career Award. Dr. Hadjicostis has served or is serving on the Editorial Boards of IEEE Transactions on Automatic Control, IEEE Transactions on Circuits and Systems (Part I), IEEE Transactions on Control Systems Technology, and International Journal of Discrete Event Dynamic Systems. He currently serves as Vice-Chair for the IFAC Technical Committees on Discrete Event and Hybrid Dynamic Systems and on Stochastic Systems.
