Eyad H. Abed is a Professor of Electrical and Computer Engineering at the
University of Maryland, College Park, where he is also affiliated with the
Institute for Systems Research. His research interests include system and
control theory with an emphasis on nonlinear systems, and applications in
electric power systems, communication networks, aerospace systems, and social
networks. Since 2014, he has been on an intergovernmental appointment as a
Program Director in the Energy, Power, Control and Networks (EPCN) Program
within the Division of Electrical, Communications and Cyber Systems (ECCS) of
the U.S. National Science Foundation. During 2002-2008, he served as Director
of the Institute for Systems Research at the University of Maryland. During
2009-2012, he served as Dean of the College of Information Technology at the
United Arab Emirates University.
Dr. Abed received the S.B. degree from the Massachusetts Institute of
Technology in 1979, and the M.S. and Ph.D. degrees in 1981 and 1982,
respectively, from the University of California at Berkeley, all in Electrical
Engineering. He is a Fellow of the IEEE, and a recipient of several awards,
including the Presidential Young Investigator Award from the National Science
Foundation, the O. Hugo Schuck Best Paper award from the American Automatic
Control Council, a Senior Fulbright Scholar Award from the Council for the
International Exchange of Scholars, the Outstanding Systems Engineering Faculty
Award of the Institute for Systems Research, the Alan Berman Research
Publication Award from the Naval Research Laboratory, and two teaching awards
from the University of Maryland. He has been on the editorial boards of the IEEE
Transactions on Automatic Control and the journal Nonlinear Dynamics.
He was also a member of the Executive Committee of the IEEE Control Systems
Society, and served as its Vice President for Financial Activities during
2007-2009. He has consulted for several corporations and government agencies in
the application of control and dynamic modeling to problems in energy, radar
and aircraft engine dynamics.
Dr. Abed's research interests include system
and control theory; electric power system dynamics and control; systems
engineering; the analysis and design of complex networks, including
communication networks and social networks; and aerospace control systems.
Among his research contributions (with his students and colleagues) in
system and control theory are the development of the bifurcation control
approach to control of nonlinear systems bordering on their stability limits;
introduction of strong D-stability and its implications for stability analysis
of multi-time-scale systems; introduction of the guardian map approach to
stability analysis of uncertain systems; contributions to the study of border
collision bifurcations; and development of a new approach to the analysis of
modal participation in linear dynamic systems.
In applications, he and his co-workers have contributed to the study
of oscillations and nonlinear dynamics of electric power systems; oscillations
in internet traffic under congestion control protocols such as TCP-RED;
redesign of computer network congestion control protocols to extend the regime
of acceptable behavior; analysis and design of artificial swarms; nonlinear
dynamics and active stall control of gas turbine jet engines; control of
tethered satellites in station-keeping and in deployment and retrieval;
modeling and control of power electronic circuits using sampled-data methods;
nonlinear modeling and control of supercavitating
bodies; control of particle accelerators; aircraft stall control; analysis and
control design for cardiac arrhythmia; and gated radar tracking system
nonlinear modeling and dynamics.
