Рассмотрена задача компенсации неизвестных внешних возмущений для класса линейных стационарных многоканальных систем с различной величиной запаздывания в каналах управления. Предполагается, что внешние возмущения представляют собой гармонические сигналы с неизвестными частотами, фазами, амплитудами и смещениями, которые одновременно воздействуют как на вход, так и на выход системы. Для решения поставленной задачи используется метод прямой компенсации возмущений, основанный на принципе внутренней модели, в сочетании с классическим методом развязки по состоянию Фальба–Воловича, что позволяет повысить скорость сходимости выходных сигналов даже при небольшом коэффициенте адаптации.</p></sec><sec><title>   Метод</title><p>   Метод. С целью устранения перекрестных взаимодействий между управляющими контурами к системе применяется метод развязки каналов на основе обратной связи по состоянию, разработанный на базе классического подхода Фальба–Воловича.

Стабилизация системы осуществляется одновременно с развязкой каналов управления, что позволяет перейти к задаче компенсации внешних неизвестных возмущений, минуя фазу проектирования стабилизирующего компонента управляющего сигнала.

It is assumed that external disturbances are harmonic signals with unknown frequencies, phases, amplitudes, and biases that simultaneously affect both the input and output of the system. To solve the problem, the direct disturbance compensation method based on the internal model principle is used in combination with the classical Falb-Wolovich linear state feedback decoupling method which allows increasing the convergence rate of output signals with a small adaptation parameter. In order to eliminate cross-interactions between control loops, the channel decoupling method based on Falb-Wolovich linear state feedback decoupling approach is applied to the system. Then, an observer is constructed to estimate the state vector of the external disturbance model and, based on the estimations, an adaptive control law with the memory regressor extension is designed to compensate for external disturbances based on the internal model principle. The system is stabilized simultaneously with the decoupling of control channels, which allows one to proceed to the problem of compensating for external unknown disturbances, bypassing the design phase of the stabilizing component of the control signal. There are no restrictions on the observability and stability of the control plant. An adaptive algorithm with the memory regressor extension combined with the Falb-Volovich linear state feedback decoupling method is proposed to compensate for unknown external disturbances for a class of linear stationary multidimensional systems with distinct control delays. The efficiency of the proposed approach is illustrated by an example of numerical simulation in the MATLAB/Simulink environment. The resulting transient response plots demonstrate that the proposed algorithm ensures the boundedness of all closed-loop signals and the asymptotic stability of the output variables in the presence of distinct input delays under external harmonic disturbances. The proposed approach allows obtaining an improved rate of convergence of processes and can be applied in engineering systems and complexes the mathematical description of which is given in the form of linear multidimensional systems with distinct input delays.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>адаптивное управление</kwd><kwd>гармонические возмущения</kwd><kwd>компенсация возмущений</kwd><kwd>развязка каналов</kwd><kwd>запаздывания в каналах управления</kwd><kwd>метод Фальба–Воловича</kwd><kwd>многоканальная система</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adaptive control</kwd><kwd>harmonic disturbance</kwd><kwd>disturbances compensation</kwd><kwd>decoupling</kwd><kwd>control delays</kwd><kwd>Falb-Wolovich method</kwd><kwd>MIMO system</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">Wang Q-G.
