Professor of St Petersburg University receives the Andronov Prize from the Russian Academy of Sciences
Nikolay Kuznetsov, Professor of St Petersburg University, Corresponding Member of the Russian Academy of Sciences, has been awarded the Andronov Prize of the Russian Academy of Sciences in the field of classical mechanics and control theory. Highly lauded is his cycle of works "Theory of hidden oscillations and stability of control systems".
The research on the theory of hidden oscillations underpins his doctoral dissertation, which focuses on the development of effective analytical and numerical methods to study hidden oscillations of dynamic systems. The theory of stability, bifurcation theory, chaos theory, control theory and up-to-date computing technologies provide a fresh look on a range of famous scientific problems and practical tasks in the field of analysis of multidimensional dynamic models, the scientist said. This led to the emergence of the theory of hidden oscillations, which reflects the current stage in the development of the theory of oscillations developed by Academician Aleksandr Andronov. This theory opened up fundamentally new ways to determine the boundaries of stability and identify oscillations to prevent technological and man-made disasters.
Receiving this award is a high assessment of the work of our entire scientific school and the scientific potential of St Petersburg University. This year, the Andronov Prize was awarded for the last time, due to the reforms in the system of the academic awards. I am its 32nd and last laureate.
Nikolay Kuznetsov, Corresponding Member of the Russian Academy of Sciences
When preparing his doctoral dissertation, Nikolay Kuznetsov made a number of innovative observations and discoveries, which are being successfully developed today by the team of the scientific school under his leadership. The methods developed within the framework of this theory identify undesirable oscillatory modes and determine the boundaries of stability in a number of well-known engineering problems. Among them are the following: the problem of Mstislav Keldysh in nonlinear analysis of flutter suppression systems for aircraft controls; the problem of Aleksandr Andronov and Ivan Vyshnegradsky in global stability of the centrifugal turbine regulator; and the problem of determining the stability of a closed nonlinear dynamic model of the control system of the hydraulic unit at the Sayano-Shushenskaya Hydro Power Plant to name just a few.
The prize was established in 1971 in honour of Member of the USSR Academy of Sciences Aleksandr Andronov (1901-1952), who was a famous specialist in electrical engineering, radiophysics and applied mechanics and a creator of the new direction in the theory of oscillations and dynamics of systems. The award is given every three years for outstanding work in the field of classical mechanics and control theory.
The results obtained were previously awarded by the St Petersburg University Prize for Scientific Works (2020) and the Afraimovich Award (2021). They are also included in the reports "On the most important scientific achievements obtained by Russian scientists in 2022" by the President of the Russian Academy of Sciences, Academician Gennady Krasnikov.
Nikolay Kuznetsov is Head of the Department of Applied Cybernetics at St Petersburg University, Head of the leading scientific school of the Russian Federation in the field of mathematics and mechanics, one of the most highly cited researchers in the world according to the Web of Science, and the author of more than 400 publications, five monographs and ten intellectual property certificates.
