National achievements in control theory

The present paper is confined only to deterministic problems in trajectory analysis, control and optimization within the framework of mathematical theory of controlled processes. The national community of researchers involved in these topics was enormous, including those in the Academy of Sciences, the Universities and the numerous institutions and plants supervised by related industrial ministries. While giving tribute to all those involved, this paper does not claim to give a full review of available publications, concentrating on what the authors believe to be the seminal issues in the field. This publication will therefore inevitably have a subjective flavor. We sincerely apologize to all those whose contributions may have been missed.
