The rate requirements for the shape calculations are especially high for tokamaks with asmall radius, such as Globus-M2 (St. Petersburg, Russia). A real-time magnetic plasma control system forthe Globus-M2 tokamak with flux and current distribution identification (FCDI) algorithm for the plasmaequilibrium reconstruction in feedback is presented. The control system contains discrete one-dimensionaland matrix proportional-integral-derivative controllers synthesized by the matrix inequality method usingthe plasma LPV model calculated on experimental data, and carries out the coordinated control of the plasmaposition and shape as well as the compensation for the scattered field of the central solenoid. The FCDI algorithmis improved for the operation in the real-time mode, and makes it possible to reconstruct the plasmashape in 20 μs. The digital control system with a feedback algorithm was simulated on a real-time test bench,consisting of two Speedgoat Performance Real-Time Target Machines (RTTM), and demonstrated the averageTask Execution Time (TET) value in 67 μs.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45257553118016">Для управления формой плазмы во время разряда в токамаке необходимо рассчитывать форму плазмы в реальном времени. Требования к скорости расчета формы особенно высоки для токамаков с небольшим радиусом, таких как Глобус-M2 (Санкт-Петербург, Россия). Представлена система магнитного управления плазмой реального времени для токамака Глобус-М2 с алгоритмом восстановления равновесия плазмы FCDI в обратной связи. Система управления содержит дискретные одномерные и матричные ПИД-регуляторы, синтезированные методом матричных неравенств на LPV‑модели плазмы, рассчитанной на экспериментальных данных, и осуществляет согласованное управление положением и формой плазмы, а также компенсацией рассеянного поля центрального соленоида. Алгоритм FCDI (Flux and Current Distribution Identification) был улучшен для работы в режиме реального времени, и позволяет восстанавливать форму плазмы за \(20\) мкс. Моделирование цифровой системы управления с алгоритмом в обратной связи было проведено на стенде реального времени, состоящего из двух целевых машин реального времени (ЦВРМ) Speedgoat Performance, и продемонстрировало среднее значение TET (Task Execution Time, время расчета за такт) в 67 мкс.</p></trans-abstract><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ferron J., Walker M., Lao L., John H.S., Humphreys D., Leuer J. // Nuclear Fusion. 1998.
