Industrial Automatic Control Systems and Controllers Annotation << Back Automation of the Process of Natural Gas Odorization Using Fuzzy Sets Zh.A. Daev, N.Z. Sultanov The paper proposes a method and system of automatic control of odorant. The proposed system is based on fuzzy set methods. To solve the problem, we introduce linguistic variables for odorant concentration, gas consumption and season with their fuzzy sets. The article provides recommendations related to the implementation of the system and method on programmable logic controllers. Keywords: odorization; natural gas; fuzzy logic; automation.
