Объектом исследований явился штамповочный пресс, который предназначен для выпуска колец различных профилей и материалов усилием 10000 тс, участвующий в технологическом цикле кольцепрокатного производства. Для моделирования типовых процессов основных элементов системы использована среда разработки TiaPortal. Реализовано повышение стабильности и качества управления подвижной траверсой главного гидрораспределителя штамповочного пресса УЗТМ 10000 тс за счет разработки и внедрения специализированных алгоритмов обработки сигналов ручного джойстика. Разработанные алгоритмы прошли апробацию на реальном оборудовании. Предложен и реализован алгоритм формирования управляющего сигнала, который ограничивает скорость его изменения до уровня, исключающего гидравлические удары, и обеспечивает S-образную форму расходной характеристики сервоклапана за счет каскадного включения апериодических звеньев первого порядка, что минимизирует переходные процессы. Проведенные испытания подтвердили, что блок обработки джойстика полностью исключает влияние зоны нелинейности, обеспечивая стабильное нулевое задание в исходном положении; блок формирования задания гарантирует плавное, безгидроударное изменение формы расходной характеристики сервоклапана по S-образной траектории. В результате модернизации удалось сократить простои оборудования на ремонт на 7 %, что подтверждает практическую эффективность и экономическую целесообразность предложенных решений. Разработанные алгоритмы и технические решения были апробированы на реальном оборудовании предприятия Челябинской области. Внедрение разработанной системы управления позволило повысить надежность работы гидрораспределителя на 5–7 %, исключить гидравлические удары и обеспечить точное позиционирование при времени открытия и закрытия до 1,5 с. Предложенное решение может быть успешно адаптировано для модернизации систем управления аналогичных гидравлических прессов и другого кузнечно-штамповочного оборудования с ручным управлением, продлевая их жизненный цикл.</p></abstract><trans-abstract xml:lang="en"><p>This study aims to improve the stability and performance of control of the moving crosshead in the main hydraulic directional control valve of a 10,000-tf forging press manufactured by Ural Heavy Machinery Plant (UZTM, Russia). The press is used to produce rings of various profiles and materials as part of the ring-rolling process. Typical processes in the main system components were modeled using the TIA Portal software platform. Improved stability and control performance were achieved by developing and implementing specialized algorithms for processing signals from the manual joystick. The algorithms were tested on the actual equipment. A control signal generation algorithm was developed and implemented to limit the rate of signal change to a level sufficient to prevent hydraulic shock and to provide an S-shaped servo-valve flow characteristic through cascaded first-order lag elements, thereby minimizing transients. Testing confirmed that the processing block for joystick input completely eliminates the effect of the nonlinear region while maintaining a stable zero setpoint in the neutral position. The setpoint generation block ensures a smooth change in the servo-valve flow characteristic along an S-shaped trajectory without hydraulic shock. The modernization reduced equipment downtime for repairs by 7 %, confirming the practical effectiveness and economic feasibility of the proposed solutions. The developed algorithms and technical solutions were validated on actual equipment at an industrial facility in the Chelyabinsk Region. Implementation of the control system increased the operational reliability of the hydraulic directional control valve by 5–7 %, eliminated hydraulic shock, and provided accurate positioning with opening and closing times of up to 1.5 s. The proposed solution can be adapted to upgrade the control systems of similar hydraulic presses and other manually operated forging and stamping equipment, thereby extending their service life.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>штамповочный пресс</kwd><kwd>автоматизация</kwd><kwd>джойстик</kwd><kwd>нелинейность</kwd><kwd>сервоклапан</kwd><kwd>компенсация</kwd><kwd>траектория</kwd></kwd-group><kwd-group xml:lang="en"><kwd>die-stamping machine</kwd><kwd>automation</kwd><kwd>joystick</kwd><kwd>nonlinearity</kwd><kwd>servovalve</kwd><kwd>compensation</kwd><kwd>trajectory</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">Романова О.А., Сиротин Д.В.
