METHODOLOGY FOR CONTROLLING THERMAL COMFORT IN A ROOM BASED ON A TWOPOSITION REGULATOR

Abstract

The article discusses the problem of ensuring thermal comfort in rooms through the use of adaptive control systems based on two-position regulators. The aim of the work is to develop and study a system that provides automatic adjustment of the regulator parameters and contributes to a reduction in energy costs. A method for controlling thermal comfort with the ability to change settings according to user requirements is proposed, as well as an algorithm for refining the parameters of a two-position controller, taking into account the type of setpoint shift. Based on the developed algorithm, a model of the thermal comfort control process in a room with automatic adjustment was created, the simulation results of which confirmed the effectiveness of the proposed solution. The system provides automatic determination of control error levels, according to which the heating is switched on and off, and the deviation of the parameters does not exceed 10% of the set limits. The use of an improved principle for calculating the error level change step improves the quality of the system's operation, although it increases the number of iterations and the adjustment time. The scientific novelty of the work lies in the creation of an adaptive thermal comfort control system that refines the initial parameters of the controller and adjusts them during operation. The practical significance lies in the possibility of using the system to improve energy efficiency and integrate the results of modelling into the training process for specialists in automation and energy management. Further development of the research involves the transition to continuous thermal comfort control using a proportionalintegral- derivative control law and automatic determination of the controller parameters.
