Conceptual Foundations for Creation of Mechatronic Control Systems for the Microclimate of Museum Premises Using Fuzzy Logic Controllers

Abstract

Abstract. A supervising algorithm based on the maintenance of the desired discomfort index (which is the intersection of two indexes: museum peaces and human body) via a fuzzy-controller dealing with museum premises’ microclimate control systems using mechatronic tools. To assess the impact of the environment on the museum peaces and on a person being in the museum premises, it is necessary to determine not only the quantitative value of the microclimate’s individual parameters, but also the result of their overall impact on the human body and museum peaces located in this area. The existing methods of integrated microclimate control by means of mechatronic systems are studied with regard to control methods. The value of such a complex index of discomfort is divided into ranges depending on the average sensation of the comfort in the museum room applicable both for the person (human flow) and museum peaces. The fundamentals of the fuzzy sets theory (Zadeh-Saati) are examined. The synthesis of fuzzy logic controller is carried out. The rules database based on the discomfort index’s calculated values is developed. An intelligent system for the automatic maintenance of comfortable microclimatic conditions in the museum premises is designed. The rule base for the fuzzy-controller is constructed on basis of discomfort complex index’s calculated values for all possible options of dry and humid thermometers’ temperature values. The control effect of the mechatronic microclimate control system of specific museum premises is produced after processing of the aggregated information coming simultaneously from two sensors, thus reducing the number of unnecessary inclusions at low oscillations of each specific parameter. At the same time, special sensors detect the number of people located in the museum premises at the given time and they adjust the operation of the computer-controlled microclimate devices designed for museum premises. Subsequent to the results of simulation, it is possible to note the compliance of the received mechatronic control system with the requirements as for obtaining the desired level of the discomfort complex index in museum premises, the minimum number of executive mechanism’s inclusions (for the currently available one at a given time and for the number of visitors to the museum premises), the lack of overregulation and the energy savings.
