Целью работы является нахождение значений компонентов модели, обеспечивающих устойчивую работу системы. Представлена методика определения состава экстремумов. Получено условие существования экстремумов, которое было проверено на конкретном примере. Высказано предположение об области, в которой невозможно с определенностью говорить об устойчивости системы. Высказана гипотеза об условии потери положения стабильного равновесия и перехода системы в новое состояние.</p></abstract><trans-abstract xml:lang="en"><p>The trilinear neighborhood model of the process of forming the temperature of hot-rolled strip coiling where the parameters are a state, control and information is considered. The purpose of the work is to find the values of the components of the model ensuring steady functioning of the system. The technique of defining the structure of the extrema is presented. The existence condition for extrema is received and checked on a concrete example. The suggestion about the area in which it is impossible to speak with definiteness about stability of the system is made. The hypothesis about a condition of the stable balance loss and of the transition of system to a new state is proposed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>окрестностная система</kwd><kwd>горячекатаная полоса</kwd><kwd>отводящий рольганг</kwd><kwd>температура смотки</kwd><kwd>общее параметрическое уравнение</kwd><kwd>neighborhood system</kwd><kwd>hot-rolled strip</kwd><kwd>run-off table</kwd><kwd>coiling temperature</kwd><kwd>general parametric equation</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">Shmyrin A.
