М. Крота. Получено разложение в матричный ряд системы уравнений Чжуа, в результате чего найдены линейное, квадратичное и кубическое матричные ядра. На основе данного разложения разработана имитационная модель электронной схемы, реализующей схему Чжуа с гладкой нелинейностью, и построены аттракторы для хаотического режима работы данной схемы. Предложенная схемотехническая реализация позволяет учитывать раздельное влияние нелинейностей высших порядков на процесс формирования хаотического режима функционирования схемы Чжуа. Это дает возможность провести серию экспериментов по исследованию модели, не реализуемых на обычной схеме Чжуа. В ходе экспериментов была обнаружена значительная корреляция между выходными сигналами кубического и квадратичного членов матричного ряда при хаотическом режиме работы схемы. Применение матричной декомпозиции в сочетании с вычислительным экспериментом позволило выявить, что модель Л. Д. Ландау начальной турбулентности (после срыва стационарного режима) достаточно хорошо описывает процесс возникновения хаотических режимов в схеме Чжуа. В частности показано, что режим жесткого самовозбуждения электрических колебаний в схеме Чжуа приводит к появлению хаотического аттрактора типа «двойной завиток» в пространстве состояний. Полученные результаты могут найти применение в задачах генерирования хаотических сигналов, в частности для решения проблем криптографии или управления мобильными роботами, а также для предотвращения возникновения хаотических режимов в работе электронных и механических устройств.</p></abstract><trans-abstract xml:lang="en"><p>The scope of this work are electric circuits or electronic devices with chaotic regimes, in particular the Chua’s circuit. A nonlinear analysis of chaotic attractors based on the Krot’s method of matrix decomposition of vector functions in state-space of complex systems has been used to investigate the Chua’s circuit with smooth nonlinearity. It includes an analysis of linear term of the matrix series as well as an estimation of influence of high order terms of this series on stability of complex system under investigation. Here the method of matrix decomposition has been applied to analysis of the Chua’s attractor. The terms of matrix series have been used to create a simulation model and to reconstruct an attractor of chaotic modes. The proposed simulation model makes it possible to separate an influence of nonlinearities on forming a chaotic regime of the Chua’s circuit. Usage of both the matrix decomposition method and computational experiment has allowed us to find out that the initial turbulence model proposed by L. D. Landau is suitable for set-up description of the chaotic regime of the Chua’s circuit. It is shown that a mode of hard self-excitation in the Chua’s circuit leads to its chaotic regime operating with a double-scroll attractor in the state-space. The results might be used to generate of chaotic oscillations or data encryption. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>нелинейная динамическая система</kwd><kwd>схема Чжуа</kwd><kwd>хаотический аттрактор</kwd><kwd>матричный ряд в пространстве состояний</kwd><kwd>матричная декомпозиция схемы Чжуа</kwd><kwd>режим жесткого самовозбуждения электрических колебаний</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nonlinear dynamical system</kwd><kwd>Chua’s circuit</kwd><kwd>chaotic attractor</kwd><kwd>matrix series in state-space</kwd><kwd>matrix decomposition of Chua’s circuit</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">Krot, A.
