Строятся асимптотические приближения к решению этой задачи в виде программы и обратной связи. Основное достоинство предлагаемых вычислительных процедур состоит в том, что при их применении исходная задача распадается на три невозмущенные задачи оптимального управления меньшей размерности.</p></abstract><trans-abstract xml:lang="en"><p>The problem of constructing a transition process with minimal energy costs for a linear singularly perturbed system containing three groups of variables with significantly different rates of change is considered. Asymptotic approximations to solving this problem are constructed in the form of an open-loop and feedback controls. The main advantage of the proposed computational procedures is that the original problem is split into three unperturbed optimal control problems of lower dimension.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>малый параметр</kwd><kwd>сингулярно возмущенная система</kwd><kwd>квадратичный функционал</kwd><kwd>оптимальное управление</kwd><kwd>обратная связь</kwd><kwd>асимптотические приближения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>small parameter</kwd><kwd>singularly perturbed system</kwd><kwd>quadratic functional</kwd><kwd>optimal control</kwd><kwd>feedback</kwd><kwd>asymptotic approximations</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">Дмитриев, М.
