Составляющие этой погрешности обусловлены динамическими свойствами (инерционностью) датчика и аддитивным шумом на его выходе. Предложен способ оценивания и уменьшения погрешности динамических измерений на основе принципа адаптивного линейного предсказания или адаптивного линейного усиления сигналов. Способ заключается в формировании сигнала оценки погрешности по результату сравнения задержанной копии восстанавливаемого сигнала с тем же восстанавливаемым сигналом, прошедшим через адаптивный нерекурсивный фильтр с линейной фазовой характеристикой. На основе данного подхода разработана структура измерительной системы, позволяющей оценивать погрешность динамических измерений и уменьшать её путём коррекции динамических характеристик датчика и адаптивной фильтрации шума измерения. Проведено компьютерное моделирование предложенной измерительной системы для датчика второго порядка. Получены оптимальные (в смысле среднеквадратичной оценки погрешности) значения порядка восстанавливающего адаптивного фильтра в присутствии аддитивного гармонического шума переменной частоты на выходе датчика. Показано, что свойства предложенной структуры измерительной системы с оценивателем погрешности динамических измерений адаптивны к параметру шума. Область применения полученных результатов – обработка результатов измерений быстропеременных процессов (в том числе в режиме реального времени), когда доминирующей является составляющая погрешности динамических измерений, обусловленная динамическими свойствами (инерционностью) датчика, а также аддитивными шумами на его выходе. Решение такой задачи актуально, например, при обработке результатов наземных испытаний космической техники.</p></abstract><trans-abstract xml:lang="en"><p>The problem of the dynamic measurement error estimation and compensation is considered. This type of error is determined by two components. The first one is due to dynamic properties (inertia) of a sensor. The second one is due to the presence of an additive noise at the sensor output. An approach to estimate and reduce the dynamic measurement error based on the signals adaptive linear prediction or adaptive line enhancement principle is proposed. The approach consists in generating a dynamic measurement error estimation signal based on comparing a delayed copy of the recovered signal with the recovered signal passed through an adaptive non-recursive filter with a linear phase characteristic. The structure of a measuring system with an adaptive linear estimator of the dynamic measurement error based on this approach has been developed. A computer simulation of the proposed measuring system for the second-order sensor is carried out. Optimal (in the sense of the mean squared deviation of the dynamic error) orders of the restoring adaptive filter are obtained in the presence of additive harmonic noise of variable frequency at the sensor output. The properties of the proposed measuring system with the dynamic measurement error estimator adaptive to the noise parameter are demonstrated. The application field of the results obtained is the measurement data processing of fast-changing processes (including real-time mode), when the component of the dynamic measurement error, caused by dynamic properties (inertia) of the sensor, as well as additive noises at its output, is dominant. The solution of such a problem is relevant, for example, when processing the results of ground tests of space technology.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>динамическое измерение</kwd><kwd>адаптивная обработка сигналов</kwd><kwd>фильтры с конечно-импульсной характеристикой</kwd><kwd>погрешность динамических измерений</kwd><kwd>адаптивное линейное предсказание</kwd><kwd>адаптивное линейное усиление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dynamic measurement</kwd><kwd>adaptive signal processing</kwd><kwd>finite impulse response filters</kwd><kwd>dynamic measurement error</kwd><kwd>adaptive linear prediction</kwd><kwd>adaptive line enhancement</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Министерства науки и высшего образования Российской Федерации (государственное задание на выполнение фундаментальных научных исследований № FENU-2023-0010 (2023010ГЗ))</funding-statement><funding-statement xml:lang="en">This work was supported by the Ministry of Science and Higher Education of the Russian Federation (project no.
