Рассмотрены два подхода, обеспечивающие сходимость ошибки оценки (т. е. отклонение между оценкой вектора состояния и истинным значением) к нулю за конечное время. Время сходимости задается разработчиком в процессе построения наблюдателя. Параметры системы предполагаются известными и стационарными, относительная степень (от измеряемого выхода и неизвестного входа) равна единице. Процесс синтеза при использовании первого подхода состоит из двух этапов. На первом этапе используются два вспомогательных наблюдателя для оценки начальных условий объекта за конечное время. На втором этапе в контур вводится третий наблюдатель для онлайн оценки вектора состояния системы. Все три наблюдателя имеют одинаковую структуру, обеспечивающую нечувствительность ко входному сигналу, но разные параметры. Второй поход заключается в агрегировании вспомогательных наблюдателей и введении оператора запаздывания для оценки вектора состояния. Данный метод обеспечивает сходимость ошибки наблюдения к нулю через время запаздывания. Статья содержит строгое математическое доказательство работоспособности полученных решений. Для демонстрации эффективности и работоспособности предложенного подхода проведено компьютерное моделирование в программной среде MATLAB Simulink. В качестве объекта рассмотрена двухканальная механическая система четвертого порядка. Результаты моделирования иллюстрируют сходимость ошибки оценки вектора состояния к нулю за конечное время, задаваемое разработчиком.</p></abstract><trans-abstract xml:lang="en"><p>The paper proposes a new method for synthesizing a full-order state vector observer for a certain class of linear stationary systems with unknown input signal. Two approaches that ensure the convergence of the estimation error (i.e., the error between the state vector estimate and the true state vector) to zero in a finite time are considered. The convergence time is set by the designer in the process of observer construction. The system parameters are assumed to be known and stationary, but the relative degree (from the measured output and the unknown input) is equal to one. The synthesis process using the first approach consists of two stages. In the first stage two auxiliary observers are used to estimate the initial conditions of the object in finite time. In the second stage, a third observer is introduced into the loop to perform online estimation of the system state vector. All the above three observers have the same structure that provides their insensitivity to the input signal, but different parameters. The second approach uses aggregation of auxiliary observers and introduce a delay operator to estimate the state vector. This method provides convergence of the observation error to zero after a delay time. The paper contains a rigorous mathematical proofs of the performance of the obtained solutions. To demonstrate the effectiveness and operability of the proposed approach computer simulation was carried out in the MATLAB Simulink software environment. A two-channel fourth-order mechanical system is considered as an plant. The simulation results illustrate the convergence of the state vector estimation error to zero in a finite time specified by the developer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наблюдатель по выходу</kwd><kwd>линейная система</kwd><kwd>конечное время</kwd><kwd>фиксированное время</kwd><kwd>внешние возмущения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>observer with unknown input</kwd><kwd>linear system</kwd><kwd>finite time</kwd><kwd>fixed time</kwd><kwd>external disturbances</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при поддержке Министерства науки и высшего образования Российской Федерации, Госзадание № 2019-0898.</funding-statement><funding-statement xml:lang="en">The research was carried out with the support of the Ministry of Science and Higher Education of the Russian Federation, State Assignment No. 2019-0898.</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">Kailath T.
