Nikolai N. Krasovskii
Since the 1950s, Nikolai N. Krasovskii has been a towering presence in the control, differential games and stability fields. His pioneering functional analysis techniques for control problems are now the basic tools for systems research. With his students, he developed an array of methods for solving feedback control problems under conflict and uncertainty, providing solutions for differential games. The Barbashin-Krasovskii theorem broadened the application of Lyapunov functions, and became a precursor for the invariance principle in stability theory. A member of the Russian Academy of Sciences, Dr. Krasovskii has written more than 250 papers and several books. He has received numerous honors including the National Lenin Prize in Science, Lyapunov Gold Medal and Lomonosov Great Gold Medal. He is head research associate at the Institute of Mathematics and Mechanics at the Ural Scientific Center in Russia.
