В отличие от известных аналогов синтезирован закон управления, представляющий собой модификацию предиктора Смита с наиболее простой реализацией, не требующей сложных методов интегрирования. Предложено достаточно эффективное решение проблемы стабилизации замкнутой системы, обеспечивающее ограниченность всех переменных состояния и экспоненциальную устойчивость положения равновесия.</p></abstract><trans-abstract xml:lang="en"><p>A new algorithm for controlling unstable linear systems with input delay is presented. Unlike known analogs, a control law is synthesized that is a modification of the Smith predictor with the simplest implementation that does not require complex integration methods. A fairly effective solution to the problem of stabilizing a closed system is proposed, ensuring the boundedness of all state variables and exponential stability of the equilibrium position.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>запаздывающее управление</kwd><kwd>предиктор Смита</kwd><kwd>управление по состоянию</kwd><kwd>неустойчивые системы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>input delay</kwd><kwd>Smith predictor</kwd><kwd>state control</kwd><kwd>unstable systems</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Российского научного фонда (проект № 25-29-00896).</funding-statement><funding-statement xml:lang="en">The work was supported by the Russian Science Foundation (project No. 25-29-00896).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Цыпкин Я.
