Исследование бифуркаций в бимодальных кусочно-гладких отображениях с использованием кусочно-линейного непрерывного отображения в качестве нормальной формы. Методы. Мы предлагаем методикy определения параметров нормальной формы на базе линеаризации кусочно-гладкого отображения в окрестности критической неподвижной точки. Результаты. На плоскости параметров численно и аналитически построена область устойчивости неподвижной точки. Показано, что эта область ограничена двумя бифуркационными кривыми: линиями классической бифуркации удвоения периода и «border collision» бифуркации. Предложена методика определения параметров нормальной формы как функции параметров кусочно-гладкого отображения. Проведен анализ «border-collision» бифуркаций с использованием кусочно-линейной нормальной формы. Заключение. Выполнен бифуркационный анализ кусочно-гладкого необратимого бимодального отображения класса Z1–Z3–Z1, моделирующего динамику системы управления с импульсной модуляцией. Предложена методика расчёта параметров кусочно-линейного непрерывного отображения, используемого в качестве нормальной формы. Рассчитаны основные бифуркационные переходы при выходе из области устойчивости как с использованием исходного отображения, так и с помощью кусочно-линейной нормальной формы. Численно доказана топологическая эквивалентность этих отображений, указывающая на достоверность результатов расчёта параметров нормальной формы.</p></abstract><trans-abstract xml:lang="en"><p>Purpose of reseach. Studyof bifurcations in piecewise-smooth bimodal maps using a piecewise-linear continuous map as a normal form. Methods. We propose a technique for determining the parameters of a normal form based on the linearization of a piecewise-smooth map in a neighborhood of a critical fixed point. Results. The stability region of a fixed point is constructed numerically and analytically on the parameter plane. It is shown that this region is limited by two bifurcation curves: the lines of the classical period-doubling bifurcation and the “border collision” bifurcation. It is proposed a method for determining the parameters of a normal form as a function of the parameters of a piecewise smooth map. The analysis of "border-collision" bifurcations using piecewise-linear normal form is carried out. Conclusion. A bifurcation analysis of a piecewise-smooth irreversible bimodal map of the class Z1–Z3–Z1 modeling the dynamics of a pulse–modulated control system is carried out. It is proposed a technique for calculating the parameters of a piecewise linear continuous map used as a normal form. The main bifurcation transitions are calculated when leaving the stability region, both using the initial map and a piecewise linear normal form. The topological equivalence of these maps is numerically proved, indicating the reliability of the results of calculating the parameters of the normal form.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кусочно-гладкое бимодальное отображение класса Z1–Z3–Z1</kwd><kwd>нормальная форма</kwd><kwd>кусочно-линейное непрерывное отображение</kwd><kwd>«border collision» бифуркации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>piecewise smooth bimodal map of class Z1–Z3–Z1</kwd><kwd>normal form</kwd><kwd>piecewise linear continuous map</kwd><kwd>"border collision" bifurcation</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">Sharkovsky A., Kolyada S., Sivak A., Fedorenko V.
