Abstract
The effect of climatic and climatic changes in different geographical areas on the types of plants, animals and objects and the importance of protecting the items has led to the study of ideas related to control of air variables in desired conditions. All of the ideas studied in this field lead to the separation of under the control area in order to reduce the effect of the environment on the control variables. This area is then modeled as a system with a defined energy and mass exchange with the environment. In the present study, thermal modeling, dynamic modeling, and control of the variables of a museum which is considered an enclosed area have been investigated. For dynamic modeling, the one-dimensional heat transfer method is used for area elements (DETECt 2.3.1 method). After dynamic modeling, temperature and humidity control have been done using model-reference and modified adaptive methods. Numerical simulation results include the behavior of the system with and without using the controller, the variation of the dynamic variables, and changes in the control signal and the adaptive gains. The results show the success of control methods in the control of temperature and humidity of the studied area.
