Разработан метод расчета устойчивых инвариантных многообразий седловых периодических орбит кусочно-гладких отображений. Основной результат сформулирован в виде утверждения.

Описан численный метод расчета устойчивых инвариантных многообразий кусочно-гладких отображений, моделирующих импульсные системы автоматического управления. Метод базируется на итерировании фундаментальной области вдоль устойчивого подпространства собственных векторов матрицы Якоби, вычисленной в седловой периодической неподвижной точке. Основу метода составляет оригинальный подход нахождения обратной функции, который состоит в сведении задачи к решению нелинейного уравнения первого порядка. Такой подход исключает необходимость решения систем нелинейных уравнений для определения обратной функции и преодоления сопутствующих при этом вычислительных проблем. Приведены примеры исследования глобальной динамики кусочно-гладких отображений с мультистабильным поведением.</p></abstract><trans-abstract xml:lang="en"><p>Purpose of reseach is of the work is to develop an algorithm for calculating stable invariant manifolds of saddle periodic orbits of piecewise smooth maps. Method is based on iterating the fundamental domain along a stable subspace of eigenvectors of the Jacobi matrix calculated at a saddle periodic fixed point. Results. A method for calculating stable invariant manifolds of saddle periodic orbits of piecewise smooth maps is developed. The main result is formulated as a statement. The method is based on an original approach to finding the inverse function, the idea of which is to reduce the problem to a nonlinear first-order equation. Conclusion. A numerical method is described for calculating stable invariant manifolds of piecewise smooth maps that simulate impulse automatic control systems. The method is based on iterating the fundamental domain along a stable subspace of eigenvectors of the Jacobi matrix calculated at a saddle periodic fixed point. The method is based on an original approach to finding the inverse function, which consists in reducing the problem to solving a nonlinear first-order equation. This approach eliminates the need to solve systems of nonlinear equations to determine the inverse function and overcome the accompanying computational problems. Examples of studying the global dynamics of piecewise-smooth mappings with multistable behavior are given.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кусочно-гладкое отображение</kwd><kwd>инвариантные многообразия седловой периодической орбиты</kwd><kwd>гомоклинический контакт</kwd><kwd>замкнутая инвариантная кривая</kwd><kwd>«final» бифуркация</kwd><kwd>бифуркация Неймарка-Сакера</kwd><kwd>квазипериодические колебания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>piecewise smooth map</kwd><kwd>invariant manifolds of the saddle periodic orbit</kwd><kwd>homoclinic contact</kwd><kwd>closed invariant curve</kwd><kwd>"final" bifurcation</kwd><kwd>Neimark-Sacker bifurcation</kwd><kwd>quasiperiodic oscillations</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Рубанов В.Г. поддержан грантом: Договор 03/19 от 03.03.2019 г. в рамках Соглашения № 075-11-2019-070 от 29.11.2019 (уникальный номер 07519SU2000000).</funding-statement><funding-statement xml:lang="en">Rubanov V.G. supported by the grant: Agreement 03/19 dated 03.03.2019 under the Agreement No. 075-11-2019-070 dated 29.11.2019 (unique number 07519SU2000000).</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">Feudel U.
