Fuzzy adaptive controller design for control of air in conditioned room

Abstract

In the paper we describe an adaptive controller for control of air in conditioned room. We know, that exist more procedures for management of change of climate air in room (for setup and maintain of optimal temperature) - classical control by using the button on/of, management by bimetallic sensors, temperature management through control elements and the like. The human body perceives the minimum temperature difference (+3/−3) in your area. Where it is necessary to maintain a constant temperature for a very long time (e.g. in offices, server rooms), we need to consider the controlled system. Control system is part of the control circuit and may be considered as transfer element with certain characteristics. In the choice of the controller and its configuration is important to know the dynamic properties of the system. The simplest is to determine the dynamic characteristics of the system obtained from the its step response. We may also use the frequency response, which is much more difficult to obtain. Dynamic properties of the control system can we mathematically to express as the relationship between the change in input (Action) and a change the output value of controlled variable. On the basis of the current research, as the most appropriate way to set up and maintain a constant temperature in room at minimum operating costs may be solution by using fuzzy adaptive controller.
