Regulation of efficiency of cold of the mnogokomrpessorny refrigeration unit on the basis of algortim of fuzzy logic

In this article the principle of algorithm development regulation cooling capacity of the refrigeration unit with multiple compressors on the theory of fuzzy sets and fuzzy logic. In recent years, process automation systems were developed models, methods and hardware based on the theory of fuzzy sets. The concept of fuzzy set - an attempt to mathematical formalization of fuzzy information to build mathematical models. At the heart of this concept is the notion that the elements that make up this set, have common properties, these properties can have a different degree, and therefore are given multiple different degree. In this approach, statements like "this element belongs to a given set of" meaningless, because you need to specify "how much" or in any degree element satisfies the properties of the set. Looking at the results of simulation, system characteristics improved. Growing stability of the system to intermittent disturbances, as well as high-frequency disturbances. Through the introduction of a system controller on fuzzy logic, it is possible during operation to change the weight of rules and conduct ancillary rules that may be associated with other parameters refrigeration cycle (boiling, condensation of refrigerants in heat exchangers), and rules can be related to the operating characteristics (type of work, depending on the time of day, or season, power-saving mode, etc.), auxiliary reactions to certain events. The majority of modern refrigeration units equipped one compressor units with position control system. This is due to the relative simplicity of their design, mounting, and with lower cost unit and its automation systems in relation to refrigeration unit with multiple compressors.
