Динамика системы определяется в форме корневого портрета. Вводится понятие доминирующего поля корневых траекторий семейства, на основе которого формулируется условие устойчивости системы. На базе особенностей конфигурации корневых портретов подобных систем и графоаналитического подхода к их анализу и синтезу формируется алгоритм расчета параметров характеристического уравнения системы, обеспечивающих ее робастную устойчивость в случае неустойчивости исходной системы. Алгоритм реализуется в графоаналитическом варианте. Исследование устойчивости семейства и синтез, в случае необходимости, новых значений параметров выполняются на основе анализа расположения доминирующего поля корневых траекторий семейства в плоскости корней системы.</p></abstract><trans-abstract xml:lang="en"><p>The paper deals with the dynamic systems with perturbed parameters described by the families of the third order characteristic polynomials having coefficients within the given intervals of values. The system dynamics is represented in the form of the root locus portrait. The notion of the root locus field of the family is introduced that is the basis for the system stability condition formulation. Root locus portrait configuration peculiarities of the systems of the kind and graphic-analytical approach to their analysis and synthesis serve as the basis for the system characteristic equation parameters calculation algorithm ensuring its robust stability in case of the given system proven unstable. Algorithm is implemented in the graphic-analytical form. System stability investigation and synthesis, in case of necessity, of the new parameters values are performed on the basis of estimation of the family root locus dominating field location character in the roots plane.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>характеристический полином</kwd><kwd>динамическая система</kwd><kwd>параметрические вариации</kwd><kwd>корневой портрет</kwd><kwd>доминирующее поле корневых траекторий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>characteristic polynomial</kwd><kwd>dynamic system</kwd><kwd>parametric variations</kwd><kwd>root locus portrait</kwd><kwd>dominating root locus field</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта БРФФИ № Ф18Р-251 «Разработка корневых методов анализа и синтеза систем управления с гарантируемой динамикой, обеспечиваемой в условиях неопределенности параметров управляемых объектов»</funding-statement><funding-statement xml:lang="en">This work was supported by the grant of the BRFFR no.
