Показано, как с помощью подхода на основе „постобрабатывающей“ настраиваемой внутренней модели можно обеспечить компенсацию гармонических внешних возмущений. Синтез алгоритма адаптации произведен на основе анализа устойчивости замкнутой системы при помощи функций Ляпунова.</p></abstract><trans-abstract xml:lang="en"><p>The problem of adaptive control of multichannel nonlinear systems with unaccounted input dynamics under parametrically uncertain disturbances is considered. It is shown how the approach based on a “post-processing” adjustable internal model can be used to provide compensation for harmonic external disturbances. The adaptation algorithm is synthesized based on the stability analysis of the closed system using Lyapunov functions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>адаптивное управление</kwd><kwd>внутренняя модель</kwd><kwd>нелинейные системы</kwd><kwd>неучтенная динамика</kwd><kwd>возмущения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adaptive control</kwd><kwd>internal model</kwd><kwd>nonlinear systems</kwd><kwd>unaccounted dynamics</kwd><kwd>perturbations</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена при финансовой поддержке Российского научного фонда (проект № 25-29-00713).</funding-statement><funding-statement xml:lang="en">This work was carried out with the financial support of the Russian Science Foundation (project No. 25-29-00713).</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">Francis B., Sebakhy O.
