Abstract

U ovom radu razmatrana je upotreba modelskog prediktivnog regulatora za upravljanje sustavom klimatizacije zone jedne zgrade koja se sastoji od nekoliko povezanih prostorija, te njegove prednosti u odnosu na postojeći sustav upravljanja. U tu je svrhu, na temelju stvarnih dimenzija i građevnih materijala, izrađen precizan matematički model toplinskog sustava promatrane zone. Korištenjem YALMIP alata i CPLEX solvera, izrađena je MATLAB funkcija MPC algoritma pomoću koje je simulirano upravljanje na izrađenom matematičkom modelu zone. Na istom modelu simulirano je i upravljanje histereznim regulatorom koji predstavlja klasični termostat trenutno ugrađen za regulaciju temperature promatrane zone. Prema simulacijskim rezultatima MPC se pokazuje kao značajno kvalitetniji način upravljanja u usporedbi s postojećim, gledajući prema odstupanju od zadane vrijednosti i korištenoj snazi za regulaciju.

Abstract (english)

This paper discusses the use of a model predictive controller to control the air conditioning system of a building zone consisting of several connected rooms, and its advantages over the existing control system. For this purpose, a precise mathematical model of the zone's thermal system was developed, based on the actual dimensions and building materials. A MATLAB function of the MPC algorithm was created using YALMIP programming tool and CPLEX solver, which was used to simulate the control on the developed mathematical model of the zone. On the same model, the control using a hysteresis controller was simulated, which represents a classic thermostat currently installed to regulate the temperature of the observed zone. According to the simulation results, the MPC proves to be a significantly better controller compared to the existing one, if we were to look at the deviation from the setpoint value and the power used for regulation.
