По мере возрастания интереса  к нечетким системам  управления все более активно разрабатываются различные  подходы к исследованию таких  систем. Одно из наиболее активно развивающихся  направлений основывается  на модификации методов оценки  областей  устойчивости нелинейных САУ, однако, при решении  большинства  практических задач  этих  знаний  недостаточно, поскольку  разработчику необходимо  обеспечить  требуемые  качественные характеристики  переходного  процесса  (и, в частности, время  регулирования). В основу предлагаемого  решения  положен  критерий   абсолютной  устойчивости для  системы  с аппроксимированной  нелинейной характеристикой нечеткого  регулятора, которая  может быть получена  непосредственно  на основе применения  метода Сугено.  В статье  разрабатывается модифицированный под нечеткую систему  управления круговой  критерий  абсолютной устойчивости Якубовича,  использующий смещенную  АФЧХ  линейной  части.  При  таком  подходе  удается  получить вполне  конструктивное решение  задачи  синтеза  параметров  нечеткого  регулятора  в частотной  области.  На  примере нечетких систем  управления со статической и астатической линейными  частями  показаны  особенности  применения разработанного  подхода  и предложены  методики  синтеза  параметров  нечеткого  регулятора.  Проведен  анализ  влияния отдельных  компонент  нелинейного  преобразования на качество  переходного  процесса, и на основе этого дан ряд практических  рекомендаций по коррекции настроек  нечеткого  регулятора, обеспечивающих требуемое быстродействие.</p></abstract><trans-abstract xml:lang="en"><p>The article is devoted to solving the problem of analysis and synthesis of a control system with a fuzzy controller (fuzzy  control system) in terms of the degree of stability. As interest in fuzzy control systems grows, various approaches to the study of such systems are being developed more and more actively.  One of the most actively developing areas is based on the modification  of methods for assessing the stability regions of nonlinear ACS, however, when solving most practical problems, this knowledge is not enough, since the developer needs to provide the required qualitative  characteristics of the transient process (and,  in particular, the control time).  Therefore, the synthesis of fuzzy  ACS  in terms of the degree of stability seems to be quite constructive, since it allows quite accurately  assessing the performance of a fuzzy ACS.  The proposed solution is based on the criterion of absolute stability for a system with an approximated  nonlinear  characteristic of a fuzzy controller, which can be obtained  directly on the basis of the Sugeno method. The article develops Yakubovich’s circular criterion of absolute stability, modified for a fuzzy control system, using a shifted  AFC of the linear part. With  this approach, it is possible to obtain  a completely  constructive  solution to the problem of synthesizing  the parameters  of a fuzzy  controller in the frequency  domain.  On the example  of fuzzy  control systems with static and  astatic linear parts, the features of the application  of the developed  approach are shown and  methods for synthesizing the parameters of a fuzzy controller are proposed. The analysis of the influence of individual  components of the nonlinear  transformation  on the quality  of the transient  process is carried out, and  on the basis of this a number  of practical recommendations are given for correcting the fuzzy controller settings that provide the required performance.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>степень  устойчивости</kwd><kwd>нечеткий  регулятор</kwd><kwd>абсолютная   устойчивость</kwd><kwd>круговой   критерий</kwd><kwd>нечеткая  модель Сугено</kwd></kwd-group><kwd-group xml:lang="en"><kwd>degree of stability</kwd><kwd>fuzzy  controller</kwd><kwd>absolute stability</kwd><kwd>circular criterion</kwd><kwd>Sugeno fuzzy  model</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">Piegat A.
