Отличительной особенностью рассматриваемого уравнения, по сравнению с классическим, является допущение о том, что неизвестные параметры являются нелинейными комбинациями от одного, а именно: каждый из неизвестных параметров является числом, полученным при возведении в степень одного неизвестного параметра. Предлагается новая упрощенная процедура поиска неизвестного параметра, позволяющая, в отличие от широко распространенного метода градиентного спуска, с одной стороны, существенно упростить алгоритм идентификации, а с другой — расширить допущения на регрессоры.</p></abstract><trans-abstract xml:lang="en"><p>The classical linear regression equation is considered, containing the measured signal in the left part and the sum of terms consisting of the product of unknown parameters and known functions (regressors) in the right part. A distinctive feature of the considered equation from the classical one is the assumption that the unknown parameters are non-linear combinations of one. Namely, each of the unknown parameters is obtained by raising one unknown parameter to a power. The article proposes a new simplified procedure for searching for the unknown parameter, which, unlike the widely used gradient descent method, allows, on the one hand, to significantly simplify the identification algorithm, and, on the other hand, to expand the assumptions for regressors.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>идентификация параметров</kwd><kwd>линейная регрессия</kwd><kwd>степенная функция параметра</kwd></kwd-group><kwd-group xml:lang="en"><kwd>identification of parameters</kwd><kwd>linear regression</kwd><kwd>exponential function of parameter</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена при финансовой поддержке Министерства науки и высшего образования Российской Федерации, грант 2019-0898.</funding-statement><funding-statement xml:lang="en">The article was prepared with the financial support of the Ministry of Science and Higher Education of the Russian Federation, grant 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">Sastry S., Bodson M.
