description Aim. Improving of control accuracy by rolling strip thickness and tension and reducing of sensitivity to changes of plant parameters based on structural-parametric synthesis of robust control by rolling mills multi-motor electric drives with parametric uncertainty. Methodology. The method of structural-parametric synthesis of robust control by rolling mills multi-motor electric drives with parametric uncertainty which improves control accuracy by rolling strip thickness and tension and reducing of sensitivity to changes of plant parameters is developed. The method based on the multi-criteria game decision in which payoff vectors are dispersions of longitudinal thickness and tension of the rolled. The calculation of the payoff vector associated with modeling of the synthesized system with different input signals and for various values of the plant parameters for various modes of operation of the system. The multi criterion game solution is calculated based on particles multiswarm optimization algorithms. Results. The results of the structural-parametric synthesis of robust control by 740 three-stand cold rolling mills multi-motor electric drives are presented. Comparisons of the strip thickness and tension accuracy of the synthesized robust system with the existing system are completed. It is showed that the use of synthesized robust controllers allowed to improve strip thickness and tension accuracy and reduce the sensitivity of the system to changes of plant parameters in comparison with the existing system. Originality. For the first time the method of structural-parametric synthesis of robust control by rolling mills multi-motor electric drives with parametric uncertainty based on multi-criteria game decision and particles multiswarm optimization algorithms to improve the control accuracy by rolling strip thickness and tension and to reduce of sensitivity to changes of plant parameters is developed. Practical value. Practical recommendations on reasonable choice of the structure and parameters of robust control by 740 three-stand cold rolling mills multi-motor electric drives to improving of control accuracy by rolling strip thickness and tension and reducing of sensitivity to changes of plant parameters are given.

Повышение точности регулирования толщины и натяжения прокатываемой полосы и снижение чувствительности к изменениям параметров объекта управления на основе структурно-параметрического синтеза робастного управления многодвигательными электроприводами прокатных станов с параметрической неопределенностью. Методология. Разработан метод структурно-параметрического синтеза робастного управления многодвигательными электроприводами прокатных станов с параметрической неопределенностью, который позволяет повысить точность регулирования толщины и натяжения прокатываемой полосы и снизить чувствительность к изменениям параметров объекта управления. Метод основан на решении многокритериальной игры, в которой вектором выигрыша являются дисперсии продольной толщины и натяжения прокатываемой полосы. Вычисление вектора выигрыша связано с моделированием синтезированной системы при различных входных сигналах, для различных значений параметров объекта управления и в различных режимах работы. Решение многокритериальной игры основано на алгоритмах оптимизации роем частиц. Результаты. Приводятся результаты структурно-параметрического синтеза робастного управления многодвигательным электроприводом трехклетьевого стана холодной прокатки 740. Проведено сравнение точности регулирования толщины и натяжения полосы в синтезированной робастной и в существующей системах. Показано, что применение синтезированного робастного регулятора позволило повысить точность регулирования толщины и натяжения полосы и снизить чувствительность системы к изменениям параметров объекта управления по сравнению с существующей системой. Оригинальность. Впервые разработан метод структурно-параметрического синтеза робастного управления многодвигательными электроприводами прокатных станов с параметрической неопределенностью на основе решения многокритериальной игры и алгоритмов оптимизации роем частиц для повышения точности регулирования толщины и натяжения прокатываемой полосы и снижения чувствительности к изменениям параметров объекта управления. Практическая ценность. Даны практические рекомендации по обоснованному выбору структуры и параметров робастного управления трехклетьевым станом холодной прокатки 740 для повышения точности регулирования толщины и натяжения прокатываемой полосы и снижение чувствительности к изменениям параметров объекта управления.  National Technical University "Kharkiv Polytechnic Institute" and Аnatolii Pidhornyi Institute of Power Machines and Systems of NAS of Ukraine 2020-10-26 Article Article application/pdf http://eie.khpi.edu.ua/article/view/2074-272X.2020.5.04 10.20998/2074-272X.2020.5.04 Electrical Engineering & Electromechanics; No. 5 (2020); 25-30 Электротехника и Электромеханика; № 5 (2020); 25-30 Електротехніка і Електромеханіка; № 5 (2020); 25-30 2309-3404 2074-272X en http://eie.khpi.edu.ua/article/view/2074-272X.2020.5.04/215144 Copyright (c) 2020 B.
