Статья посвящена настройке ПИ-регуляторов в системах управления сложными процессами на энергоблоках АЭС.</p></sec><sec><title>Метод</title><p>Метод. Подчеркнуто применение методов теории автоматического управления для синтеза цифровых регуляторов, что упрощает проектирование. Особое внимание уделено преимуществам наладки регуляторов с использованием аналитических тренажеров. Они позволяют моделировать различные режимы работы, включая нештатные ситуации, что помогает устранить проблемы, такие как интегральное насыщение или потери устойчивости. Аналитические тренажеры ускоряют настройку, снижая затраты и повышая точность.</p></sec><sec><title>Результат</title><p>Результат. Рассмотрены ключевые параметры настройки: коэффициент усиления (KP) и постоянная времени интегрирования (TN), влияющие на чувствительность и скорость реакции системы. Учтены ограничения оборудования, такие как мощность нагревателей и точность измерений. Описан модуль регулятора 1411 в ПТК ТПТС-НТ, обеспечивающий высокую точность и быстродействие благодаря циклу 23,3 мс и частотному диапазону до 21,5 Гц. Это позволяет эффективно обрабатывать входные воздействия и возмущения.</p></sec><sec><title>Вывод</title><p>Вывод. Сочетание ПТК ТПТС-НТ и аналитических тренажеров обеспечивает высокую точность, адаптивность и надежность систем управления, что критически важно для сложных процессов, таких как управление энергоблоками АЭС.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. The article focuses on the tuning of PI controllers in control systems for complex processes, such as those in nuclear power plant units.</p></sec><sec><title>Method</title><p>Method. The application of automatic control theory methods for synthesizing digital regulators is emphasized, simplifying the design process.Special attention is given to the advantages of tuning regulators using analytical simulators. They allow modeling various operating modes, including emergency situations, helping to eliminate issues such as integral windup or loss of stability. Analytical simulators accelerate the tuning process, reducing costs and improving accuracy.</p></sec><sec><title>Result</title><p>Result. Key tuning parameters are discussed: the gain coefficient (KP) and the integration time constant (TN), which affect thesystem's sensitivity and response speed. Equipment  ch as heater power and measurement accuracy, are taken into account. The regulator module 1411 in the PTC TPTS-NT software-hardware complex is described, providing high precision and speed due to a cycle time of 23.3 ms and a frequency range of up to 21.5 Hz. This enables effective processing of input signals and disturbances.</p></sec><sec><title>Conclusion</title><p>Conclusion. The combination of the TPTS-NT software and analytical simulators ensures high accuracy, adaptability, and reliability of control systems, which is critical for complex processes such as nuclear power plant unit control.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ПИ-регулятор</kwd><kwd>автоматическое управление</kwd><kwd>настройка регуляторов</kwd><kwd>коэффициент усиления</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Proportional-Integral controller</kwd><kwd>Automatic control</kwd><kwd>controller tuning</kwd><kwd>proportional gain</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">Squassoni S.
