RESEACH ACTIVITY AND RESULTS

The research activity is concerned with mathematical methods and models for the qualitative control and observations theory for complex dynamical systems with after-effect.  The main achievements in this field are the following: development of an algebraic approach to solving the relative controllability problem for linear dynamical systems with retarded argument (1971-1976); solution of the problem of Krasovskii of complete controllability (total quieting) of linear dynamical systems with time delay (1977); statements and mathematical methods for the solution of the modal control problem (pole assignment) for difference-differential control systems both with complete and incomplete state information (1976-1981) and for functional-differential systems with distributed delay (1990-1993); mathematical methods and criteria for pointwise (multipoint) controllability and observability of linear difference-differential systems and relation to controllability and observability of one-parametric systems without delay (1978-1989); canonical representations for linear dynamical systems with retarded argument (1978-1984, 1988-1990); development of the general minimal state approach to the investigation of the problem of controllability and observability for general functional-differential systems of neutral type (1984-1986); feedback control (stabilization, modal control, classification, reconstruction and others) for several classes of controlled systems by using various kinds of feedback controllers such as difference controllers, integral ones and others (1991-1998);  mathematical problems of realization of time-delay systems (1999-on);hybrid systems: solution representations, controllability, observability, duality, stability and stabilization (1999-on); observability of nonlinear systems (2000-on);  scale realization of dynamical systems with after-effect (2002-on); discrete-continuous hybrid dynamical systems: stability, stabilization, controllability, reachability, observability, duality (2012-on).  It should be noted that the main mathematical methods used to solve the problems above can be successfully applied to other more general classes of dynamical systems, in particular, to descriptor and hybrid systems and to systems withmultidimensional” time (2-D Systems).
