Это свойство систем называется мультистабильностью. В мультистабильных системах может произойти внезапный переход к нежелательным или неизвестным аттракторам. Такой переход может привести к катастрофическим событиям. Оказалось, что мультистабильность также связана с возникновением непредсказуемых аттракторов, которые называются скрытыми аттракторами. Аттрактор называется скрытым, если его область притяжения не пересекается с небольшими окрестностями неустойчивойнеподвижной точки. Одной из определяющих причин изучения мультистабильных хаотических систем с различными характеристиками является широкий спектр их потенциальных инженерных приложений – в теории управления, информатике, криптологии, искусственных нейронных сетях, шифровании изображений, защищенной связи и обнаружении слабых сигналов. В последние годы исследователи обратились к разработке методов искус-ственного конструирования систем с желаемой динамикой. В этом случае основные усилия сосредоточены на создании систем с бесконечным числом сосуществующих аттракторов- экстремально мультистабильных и мегастабильных систем. Оказалось, что такие системы открывают новые возможности для решения некоторых прикладных задач, например,для реализации контроля амплитуды и полярности сигнала в инженерных системах или для создания новых систем шифрования изображений. В этой статье строится новая глад-кая трехмерная динамическая система, обратимая во времени, содержащая аналитическое решение и странный мультифрактальный скрытый аттрактор. Бассейн притяженияаттрактора включает почти все трехмерное пространство, а его размерность "почти 3".Путем замены одной из переменных системы на периодическую функцию этой переменной,строится система, обладающая 1-D полосой срытых хаотических аттракторов размерности "почти 3"и одновременно бесконечным числом аналитических решений. Специальное преобразование последней системы позволяет построить систему с 2-D полосой скрытыхаттракторов.</p></abstract><trans-abstract xml:lang="en"><p>Many real dynamical systems are characterized by the presence of a set coexisting attractors.This property of systems is called multistability. In multistable systems, a sudden transition to unwanted or unknown attractors can occur. Such a transition can lead to catastrophic events. Itturned out that multistability is also associated with the emergence of unpredictable attractors, which are called hidden attractors. An attractor is called hidden if its area of attraction does not intersect with small neighborhoods of an unstable fixed point. One of the defining reasons for studying multistable chaotic systems with different characteristics is a wide range of their potential engineering applications - in control theory, computer science, cryptology, artificial neural networks, image encryption, secure communication, and weak signal detection. In recent years, researchers have turned to developing methods for artificially designing systems with desired dynamics. In this case, the main efforts are focused on creating systems with an infinitenumber of coexisting attractors - extremely multistable and megastable systems. It turned out that such systems open up new possibilities for solving some applied problems, for example, for realizing control of the signal amplitude and polarity in engineering systems or for creating new image encryption systems. In this paper, a new smooth three-dimensional dynamical system is constructed, reversible in time, containing an analytical solution and a strange multifractal hidden attractor. The basin of attraction of the attractor includes almost all three-dimensional space, and its dimension is "almost 3". By replacing one of the variables of the system with a periodic function of this variable, a system is constructed that has a 1-D strip of hidden chaotic attractors of dimension "almost 3"and, at the same time, an infinite number of analytical solutions. A special transformation of the latter system allows us to design a megastable system with a 2-D strip of hidden attractors.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>динамические системы</kwd><kwd>аналитические решения</kwd><kwd>хаос</kwd><kwd>мегастабиль- ность</kwd><kwd>скрытые аттракторы</kwd><kwd>показатели Ляпунова</kwd><kwd>размерность Каплана-Йорке.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dynamical systems</kwd><kwd>analytical solutions</kwd><kwd>chaos</kwd><kwd>megastability</kwd><kwd>hidden attractors</kwd><kwd>Lyapunov exponents</kwd><kwd>Kaplan-Yorke dimension.</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">Rossler O., Adryaman Y., Shaukat S. and all.
