Для решения этой задачи вводится ряд реалистичных допущений, предполагающих, что параметры объекта являются полиномиальными функциями времени с неизвестными коэффициентами. Задача синтеза наблюдателя решается в классе идентификационных методов, предусматривающих преобразование исходной линейной динамической математической модели объекта к линейной статической регрессии, в которой вместо неизвестных постоянных параметров присутствуют переменные состояния генераторов, моделирующих нестационарные параметры. Для восстановления неизвестных функций регрессионной модели используется хорошо зарекомендовавший себя в последнее время метод динамического расширения и декомпозиции (смешивания) регрессора, позволяющий получать монотонные оценки, а также обеспечивающий ускорение сходимости оценок к истинным значениям. Несмотря на то, что в статье решается задача синтеза наблюдателя переменных состояния, стоит отметить возможность использования предлагаемого подхода для решения самостоятельной и актуальной задачи оценивания неизвестных нестационарных параметров.</p></abstract><trans-abstract xml:lang="en"><p>The article deals with the problem of state observer design for a linear time-varying plant. To solve this problem, a number of realistic assumptions are considered, assuming that the model parameters are polynomial functions of time with unknown coefficients. The problem of observer design is solved in the class of identification approaches, which provide transformation of the original mathematical model of the plant to a static linear regression equation, in which, instead of unknown constant parameters, there are state variables of generators that model non-stationary parameters. To recover the unknown functions of the regression model, we use the recently well-established method of dynamic regressor extension and mixing (DREM), which allows to obtain monotone estimates, as well as to accelerate the convergence of estimates to the true values. Despite the fact that the article deals with the problem of state observer design, it is worth noting the possibility of using the proposed approach to solve an independent and actual estimation problem of unknown time-varying parameters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нестационарные линейные системы</kwd><kwd>идентификация полиномиальных параметров</kwd><kwd>метод динамического расширения и смешивания регрессора</kwd><kwd>синтез наблюдателей состояния</kwd></kwd-group><kwd-group xml:lang="en"><kwd>LTV systems</kwd><kwd>identification of polynomial parameters</kwd><kwd>dynamic regressor extention and mixing (DREM)</kwd><kwd>state observer design</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">Pyrkin A.
