Abstract

U ovom radu obrađeno je upravljanje temperaturom 4 susjedne mikroklimatske zone naprednog staklenika pomoću MATLAB/Simulink simulacijskog okruženja. Uz 8 ventilatora, 2 grijača i 4 senzora odrađeno je eksperimentalno mjerenje odziva hlađenja svake mikroklimatske zone. Detaljno je opisan proces biranja parametara za mjerenje. Dobiveni odzivi su sekvencionirani i pomoću MATLAB System Identification modula izračunato je 16 prijenosnih funkcija. MATLAB PID Tunerom izračunati su parametri regulatora potrebni za funkcionalan sustav upravljanja, uzimajući u obzir problem viševarijabilnog spregnutog procesa. Kao prilika za buduća istraživanja ostavljena je mogućnost upravljanja razinom vlage.

Abstract (english)

In this paper, the temperature control of 4 adjacent microclimatic zones of an advanced greenhouse using the MATLAB / Simulink simulation environment is discussed. With 8 fans, 2 heaters and 4 sensors, experimental measurement of the cooling response of each microclimatic zone was performed. The process of selecting measurement parameters is described in detail. The responses obtained were sequenced and 16 transfer functions were calculated using the MATLAB System Identification module. MATLAB PID Tuner calculated the controller parameters required for a functional control system, taking into account the problem of multivariable coupled process. The possibility of managing the moisture level was left as an opportunity for future research.
