 Title of the article GAS REDUCTION MANAGEMENT IN HIGH-PRESSURE GAS MAINS WITH THE USE OF FUZZY LOGIC APPARATUS Authors Kryukov Vladimir Viktorovich, Postgraduate student, Orenburg State University (13 Pobedy avenue, Orenburg, Russia), E-mail: krykov56@rambler.ru Tugov Vitaliy Valer'evich, Candidate of engineering sciences, associate professor, sub-department of management and computer science in technical systems, Orenburg State University (13 Pobedy avenue, Orenburg, Russia), E-mail: sau@mail.osu.ru Index UDK 681.51:621.646.4:622.691.4.053 DOI 10.21685/2072-3059-2019-1-5 Abstract Backgrounds. The article suggests a new approach to the development of valve control systems - a high-pressure regulator using fuzzy logic devices. The developed algorithm of valve control in the SCADA-module in the built-in ST language is described, which allows to better control the technological regime of gas pressure reduction. Materials and methods. To solve this problem, the article used methods of control theory, in particular, control theory based on fuzzy logic. A mathematical model of the process of reducing gas pressure in a gas pipeline with a variable mode of operation using a fuzzy regulator was developed. Results. A mathematical description of the gas reduction process based on the fuzzy logic method has been made, as well as the valve control algorithm in the ST language (structured text) has been developed. Conclusions. Using this control algorithm based on fuzzy logic allows you to take into account the accumulated experience of specialists, which allows you to better manage the process, in contrast to the PID control, and as a result, does not require constant adjustment of the PID controller coefficients.
