Use of the indistinct regulator in automatic control systems of air of distributive installations

Introduction of cryogenic technology in different spheres of science causes the necessity of automation of cryogenic technology. Rational management of working processes that are realized by machines of cryogenic technology and the same control of technologic process. Procuring reliable and trouble-free work of equipment marks the respective system of automation. The cryogenic plants and particulary the air separation plants are quite powerconsuming. That is why their automation, ways of increasing the level of use of technical equipment, increasing of quality production, reducing the cost of production, improvement of working conditions and reduction of service, are very important. Automation is important for the further development of cryogenic technology and equipment for gas separation Particularly relevant are the development and application of automated maintenance of the most advantageous mode with different performance on split gas and air at varying energy consumption and other environmental conditions. This is all the more important, the higher the productivity of the plant, as the deviation from the optimum in this cast may lead to tangible losses due to increased energy consumption, which, in turn, will affect the increasing cost of natural gas (nitrogen, oxygen). The main equipment that is using in automation system are the serially made by industry arsenal of measuring and control. As a rule for correct system work it is required a right choosing and set up regulators. Then we sometimes have to use some seldom using methods of regulation and search. For example ? searching of optimal settings based on fuzzy logic.
