Несмотря на наличие большого числа научных публикаций в данной области, практические системные результаты получены только для односвязных систем с одним входом и одним выходом. Проблемы сходимости итерационных алгоритмов сужения множества допустимых решений и консервативности законов реконфигурации, построенных с использованием весовых матриц, не позволяют решить задачу учета таких ограничений в общем виде. Для сложных многосвязных систем до сих пор общепринятых универсальных подходов не существует. В работе ограничения на отклонения рулевых поверхностей предлагается учитывать по мощности затрачиваемого на реконфигурацию управления. Показывается, как за счет незначительной модификации метода псевдообращения можно получать приближенные псевдообратные (субоптимальные) решения с заранее известными для заданной степени приближения минимально возможными мощностью (нормой матрицы компенсации отказов) и ошибкой (нормой матрицы погрешности) реконфигурации. Это позволяет согласованно понижать мощность и повышать ошибку реконфигурации в несколько шагов вплоть до получения допустимого решения. За счет увеличения ошибки решения задачи на каждом шаге появляется дополнительная свобода в уменьшении мощности реконфигурации. Уменьшение мощности реконфигурации приводит к уменьшению амплитуд отклонений рулевых поверхностей, на которые перераспределяются сигналы с отказавших каналов управления. На модельном примере реконфигурации комплексной системы управления самолета при отказе привода стабилизатора показывается, что псевдообратное решение задачи реконфигурации приводит к значительному выходу элеронов за ограничения и потере управляемости. Решение, рассчитанное с учетом ограничений на управление, снижает в несколько раз отклонения рулевых поверхностей и обеспечивает эффективное решение задачи в допустимой области мощности и ошибки реконфигурации.</p></abstract><trans-abstract xml:lang="en"><p>The aircraft integrated control system reconfiguration laws under failures of actuators, calculated disregarding physical constraints on control surfaces saturation, can lead to a complete loss of aircraft controllability and stability. Despite the large number of scientific publications in this field, practical systematic results have been obtained only for SISO (single input – single output) systems. Problems of the convergence of iterative algorithms restricting the set of admissible solutions and the conservatism of the reconfiguration laws designed using weight matrices do not allow solving this problem in general. For complex MIMO (multi input – multi output) systems there is still no widely accepted universal approach. In this work, control surfaces constraints are regarded in terms of the power of reconfiguration control. It is shown that by slight modification of pseudoinverse (optimal) solution it is possible to obtain approximate pseudoinverse (suboptimal) solutions with priory known minimum power (compensation matrix norm) and error (residual matrix norm) of the reconfiguration for a given degree of approximation. This allows for a multistep consistent reduction in power and increasing in error of reconfiguration, until an acceptable solution is obtained. By providing the greater reconfiguration error at each step we have additional freedom in reducing the reconfiguration power. This leads to a decrease in the amplitude of the deviations of the control surfaces, to which the signals from the failed control channels are redistributed. The simulation example of the aircraft integrated control system reconfiguration under the stabilizer’s actuator failure is presented. It is shown that the pseudoinverse reconfiguration problem solution leads to the significant ailerons’ constraints violation and the loss of aircraft controllability. Regarding control constraints solution reduces several times the deviation of the control surfaces and provides an effective problem solution in the permissible power and error reconfiguration range.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>реконфигурация</kwd><kwd>комплексная система управления</kwd><kwd>отказы приводов</kwd><kwd>ограничения на управление</kwd><kwd>приближенное псевдообратное решение</kwd><kwd>мощность реконфигурации</kwd><kwd>ошибка реконфигурации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reconfiguration</kwd><kwd>integrated control system</kwd><kwd>actuator failures</kwd><kwd>control constraints</kwd><kwd>approximate pseudoinverse solution</kwd><kwd>reconfiguration power</kwd><kwd>reconfiguration error</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке РФФИ, гранты № 17-08-01445а, 18-08-00453а</funding-statement><funding-statement xml:lang="en">The study was conducted with support of the Russian Foundation for Basic Research, grants №17-08-01445а and №18-08-00453а</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">Zolghadri A.
