Abstract

In many applications one is faced with the task of simulating or controlling omplex dynamical systems. Such applications include for instance, weather prediction, air quality management, VLSI chip design, molecular dynamics, active noise reduction, chemical reactors, etc. In all these cases complexity manifests itself as the number of first order differential equations which arise. For the above examples, depending on the level of modeling detail required, complexity may range anywhere from a few thousand to a few million first order equations, and above. Simulating (controlling) systems of such complexity becomes a challenging problem, irrespective of the computational resources available. In this talk we will first briefly describe some motivating examples; we will then define the problem in mathematical terms and sketch several methodologies for its solution. The talk will conclude with open problems and directions for future research.

Biographical Information

Thanos Antoulas was born in Athens, Greece. He studied at the ETH Zürich, where he obtained the Diploma of Electrical Engineering in 1975, the Diploma of Mathematics in 1975, and the Ph.D. Degree in Mathematics in 1980. He was Professor R.E. Kalman's only Ph.D. student in Switzerland. Since 1982 he has been with the Department of Electrical and Computer Engineering, Rice University, where he is currently a Professor. Professor Antoulas was elected Fellow of the IEEE (Institute of Electrical and Electronics Engineers) in 1991 and was awarded the Best Paper Prize of the AIAA (American Institute of Aeronautics and Astronautics) Guidance, Navigation and Control Section, in 1992. In 1995 he was awarded a JSPS (Japan Society for the Promotion of Science) Fellowship. He has served on the Editorial Board of many journals including the IEEE Transactions on Automatic Control, SIAM Journal on Control and Optimization, and Linear Algebra and its Applications. For the past 8 years he has been serving as Editor-in-Chief of Systems and Control Letters. He has held many visiting appointments, including those at the Australian National University, the University of Groningen, the Catholic University of Leuven and Louvain-la-Neuve, the Tokyo Institute of Technology, Kyoto University, etc. Furthermore he has given invited presentations at numerous conferences and workshops. His research interests are in the broad area of dynamical systems and computation including model reduction of large-scale systems. He is the author of a book on the Approximation of large-scale systems, published by SIAM.
