Subject:
The parametric resonance theory and new approaches to the stability theory of nonlinear systems and to the optimization theory were developed. Among the contributions there are the quadratic criterion for absolute stabi lity, "Frequency theorem", the method of "recursive aim inequalities" in adaptive control and an abstract theory of optimal control, extending the Pontrjagin maximum principle to many new cases. Lemma Kalman-Yakubovich permits to connect two methods of control theory: frequency method and Liapu nov method. It is also of importance in stochastic realization theory. These theoretic investigations finds an application in many applied problems including robotic, mechanical engineering and electric energetics. The main results in recent years concern new aspects of linear-quadratic optimization problems.

D.Sci. thesis was defended in 1959. The author of more than 300 papers and coauthor of seven books in different areas of applied mathematics and control theory.
Member of Russian Academy of Nature Sciences from 1992 and a member of Russian Academy of Nonlinear Sciences from 1997. I was awarded a Premium for the pedagogical art by the Sankt Petersburg University (1986). I was awarded the Norbert Wiener Prize (1991), a Premium by the international editorial company "Nauka" for best publication in its journals (1995), and the IEEE Control Systems Award "For pioneering and fundamental contributions to stability analysis and optimal control"(1996). My result on the solution of certain special matrix inequalities published in Doklady AN SSSR in 1962 is included in a millennium volume "Twenty-Five Seminal Papers in Control" containing the papers that have had a major impact on the field.
