Applicatrion of fuzzy logic in control systems are heat substation

Abstract: Automatic control of substations as part of the heating system with central heating systems described in this working paper, is set down as regulation of the temperature in the secondary heating installation (radiators) depending on the outside temperature.The main purpose of the automatic control of heating substation is to achieve the desired temperature heated building (housing).In this working paper is presented how the automatic regulation of substations fully functional as a whole, using two types of regulators with completely different way of logic.Graphical diagrams of 3's facilities, which are considered real values measured in real giving time, complete the visual representation of how it performs and what is essentially an automatic regulation of substations achieved by using the regulator Siemens RVD 230.Detailed description of the stages of creating fuzzy logical regulator used for automatic control of the substations, created a new look in achieving the desired temperature that is entering the heating element, or regulation for maximum exploitation of the heat energy
