Abstract

The thesis on Candidate Degree in Technical Sciences: Specialty 05.13.03 – management systems and processes. – National Technical University «Kharkov Polytechnic Institute», Kharkov, 2018. The thesis is devoted to the development and improvement of energy-efficient control methods of distributed thermal objects for using in heat supply systems. The thesis proposes a control method of thermal objects with distributed parameters with prediction filter, where the PWM signal is used as the control action. The method of controlling thermal objects with distributed parameters with prediction using the step function as control effect has been further developed. The paper presents a formalized description of predictive control methods that allow to control temperature of an object with distributed parameters instead of object with lumped parameters temperature control at n points with p heaters. A simulation room model based on measurements of the room and the finite element method in the ANSYS environment was constructed. Using developed predictive controller, experiments of maintaining the assigned daily temperature mode were carried out. The developed method of PWM predictive control with continuous control, two-position, PID-control was compared. Experiments of maintaining the set temperature of the steel hollow rod and the sterilizer chamber using the developed software and hardware complex, based on the microcontroller AtMega 16 and PWM with prediction control method, were carried out.
