Abstract

Synchronization is an interesting dynamical phenomenon first described in the 17th century by Christian Huygens. It was studied intensively in physics and mechanics in the 20th century. The first book entirely devoted to synchronization was published in 1971 by Ilya Blekhman (IPME, St.Petersburg) who discovered the phenomenon of self-synchronization of rotors. In the 1990s an interest in synchronization of chaotic systems was growing. During recent decades synchronization has attracted a substantial interest among the control community, especially in physics-related studies (cybernetical physics), in communication by means of chaotic signals and in information control.

In the talk a number of synchronization related results will be presented, including synchronization of pendula chains, adaptive observer-based synchronization of chaotic systems and synchronization under information constraints.

Biographical Information

Alexander L. Fradkov received the Diploma degree in mathematics from the Faculty of Mathematics and Mechanics of St. Petersburg State University in 1971; Candidate of Sciences (Ph.D.) degree in Engineering Cybernetics  from St.Petersburg Mechanical Institute 1975 and Doctor of Sciences degree in Control Engineering in 1986 from St.Petersburg Electrotechnical Institute. In 1987 he became Professor of Computer Science with BSTU. Since 1990 he has been the Head of the Laboratory of Complex Systems Control of the Institute for the Problems of Mechanical Engineering of Russian Academy of Sciences. He is also a part time professor with the Faculty of Mathematics and Mechanics of St.Petersburg State University (Dept. of Theoretical Cybernetics).

Alexander Fradkov’s research interests are in the fields of nonlinear and adaptive control and control of oscillatory and chaotic systems. He is also working in the boundary field between Physics and Control (Cybernetical Physics). He is coauthor of 450 journal and conference papers, 10 patents, 16 books and textbooks.

Alexander Fradkov is the Vice-President of the St.Petersburg Informatics and Control Society, Member of the Russian National Committee of Automatic Control, IEEE Fellow. He is a member of IEEE CSS Conference Editorial Board (1998-2008); a member of the IFAC Policy Committee and Vice-Chair of the IFAC Technical Committee on Adaptive Control. He organized and co-chaired 1st and 2nd IEEE-IUTAM-EPS Conferences "Physics and Control" in 2003, 2005 and in 2005 he was elected as the President of the IPACS (International Physics And Control Society).
