A criterion of constructive identifiability and complete controllability of linear stationary systems of neutral type

For linear stationary systems of neutral type, parametric criteria of constructive indentifiability and complete controllability are proved and constructive methods for solving these problems are presented. This paper is a continuation of work [1], where constructive solutions to the problem of complete controllability and identifiability were given for the case of a characteristic quasi-polynomial of the delayed type and the corresponding literature was presented; therefore, the historical notes concerning the problems studied are omitted in this paper.
