Новую отказоустойчивую структуру целесообразно использовать для устройств автоматики с комбинационной логикой. При синтезе отказоустойчивой структуры применяется метод паритета для установления факта возникновения неисправности в контролируемом объекте и метод логического дополнения для определения неправильно вычисленных выходных функций и формирования сигналов для их коррекции. Приведена структурная схема системы с коррекцией ошибок и дано ее описание. Представлен алгоритм синтеза контрольного оборудования с минимизацией сложности его технической реализации. Результаты экспериментов с контрольными комбинационными схемами подтверждают высокую эффективность применения предложенной структуры системы с коррекцией ошибок.</p></abstract><trans-abstract xml:lang="en"><p>Simpler than known structure of the system with error correction in calculations is proposed based on duplication and triplication of blocks with majority principle of choosing the values of signals. It is advisable to use the new fault-tolerant structure for automation devices with combinational logic. In fault-tolerant structure synthesis, the parity method is used to establish the fact of a fault in the main logic unit and the logical complement method is used determine incorrectly calculated output functions and to generate signals for their correction. The method also allows to adjust the values of incorrectly calculated functions. Structural diagram and description of error correction system are given. The synthesis algorithm of control equipment is described with minimization of the technical implementation complexity. The experiment results with control combinational circuits are given, confirming the high efficiency of proposed system structure with error correction.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>комбинационные устройства автоматики</kwd><kwd>системы с обнаружением неисправностей</kwd><kwd>системы с коррекцией ошибок в вычислениях</kwd><kwd>отказоустойчивые системы</kwd><kwd>дублирование</kwd><kwd>троирование</kwd><kwd>мажоритарный принцип контроля</kwd><kwd>метод логического дополнения</kwd><kwd>код паритета</kwd></kwd-group><kwd-group xml:lang="en"><kwd>combinational automation devices</kwd><kwd>fault-detection systems</kwd><kwd>systems with error correction in calculations</kwd><kwd>fault-tolerant systems</kwd><kwd>failure redundancy</kwd><kwd>triplication</kwd><kwd>majority control principle</kwd><kwd>Boolean complement method</kwd><kwd>parity code</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">Согомонян, Е.
