Summary: [For the entire collection see Zbl 0559.00028.]
The paper deals with the problems of controllability and observability of delay-differential systems which directly generalize the corresponding problems for ordinary linear dynamic systems without delay. We introduce a number of definitions which define more exactly a notion of the state for hereditary systems as the minimal part of data needed for generating a unique trajectory of the system. We also introduce a notion of informator for the characterization of states and generalize the well- known Lagrange’s identity to systems with delay. This result is used for the investigation of some controllability problems of delay functional systems. Dual results and the problem of computation of the minimum number of outputs needed for \(\infty\)-observability of the system is also presented.
