Цель статьи — разработка метода синтеза субоптимального управления, обеспечивающего высокую точность приведения выхода системы в заданное значение к фиксированному моменту времени. Обсуждается дальнейшее развитие метода обратного интегрирования уравнения Риккати с зависящими от состояния коэффициентами за счет использования терминального регулятора, синтезированного для вспомогательной задачи управления в обратном времени, для определения состояния системы при обратном интегрировании вместо стандартного стабилизирующего регулятора (SDRE-регулятор). Эффективность метода проверена на эталонной задаче управления осциллятором Ван дер Поля. Приведены результаты моделирования, демонстрирующие более высокую точность предложенного терминального метода обратного интегрирования по сравнению с классическим подходом, использующим SDRE-регулятор, и сопоставимость с итерационным методом аппроксимирующей последовательности уравнения Риккати по точности. Метод рекомендован для задач точного управления сложными объектами на конечных интервалах времени.</p></abstract><trans-abstract xml:lang="en"><p>The problem of precise terminal control of nonlinear systems with State-Dependent Coefficients (SDC) over a finite time interval is solved. The purpose of the article is to develop a method for synthesizing suboptimal control, which ensures high accuracy of bringing the system output to a set value by a fixed point in time. Further development of the method of inverse integration of the Riccati equation with state-dependent coefficients is discussed by using a terminal controller synthesized for the auxiliary control problem in reverse time to determine the state of the system during reverse integration instead of the standard stabilizing regulator (SDRE regulator). The effectiveness of the method is been tested on the reference task of controlling the Van der Pol oscillator. The simulation results are presented, demonstrating a higher accuracy of the proposed terminal method of inverse integration compared with the classical approach using the SDRE controller, and comparability with the iterative method of approximating the sequence of the Riccati equation. The method is recommended for the tasks of precise control of complex objects at finite time intervals.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нелинейные системы</kwd><kwd>уравнение Риккати</kwd><kwd>терминальное управление</kwd><kwd>оптимальная система</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nonlinear systems</kwd><kwd>Riccati equation</kwd><kwd>terminal control</kwd><kwd>optimal system</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pearson J.
