The thesis is devoted to the analysis of distributed thermal objects control using prediction systems to determine their disadvantages and development of new energy-efficient heat control methods for administrative and office buildings. The aim of the thesis is to develop new methods of energy saving control with prediction for heat objects with distributed parameters for increasing energy efficiency of buildings. The object of the research is the processes of control the heat-efficient modes of administrative and office buildings. Methods: mathematical and experimental methods of research based on PWM control with prediction. Theoretical and practical results: a method of software control of thermal objects with distributed parameters using pulse-width modulation with prediction (Ukrainian patent № 81276) has been developed. A hardware-software complex for obtaining transient characteristics of thermal objects, calculation of thermal influences coefficients and maintaining a given temperature in the room was developed. A computer model of the premises that allows simulating a thermal object in different operating modes was created. Novelty: the method of energy-saving PWM control of distributed thermal objects with prediction with improved control accuracy was developed. The control method of thermal object with distributed parameters using a step function have been further developed. Formulas that allow refusing from an object with lumped parameters control to an object with distributed parameters control have been developed. Degree of introduction: the results of scientific research were introduced into the practice of designing systems for automatic control of thermal objects, technological processes of the enterprise VO OWEN (Kharkiv). The materials of the dissertation are used in lecture courses "Theory of automatic control" and "Software tools of control systems" at the department automation and control systems NTU "KhPI". Application sphere – in enterprises that develop or modernize existing high-performance control systems for distributed thermal objects. In higher educational establishments for engineer profile specialists training.
