Abstract

Fokus ovog rada je na regulaciji unutrašnje temperature malenog staklenika. Prvo je na temelju zakona dinamike toplinskih procesa izrađen vjeran matematički model u MATLAB-u. Na tom modelu provedene su simulacije za razne uvjete i parametre koji utječu na temperaturu unutar staklenika. Tako su odabrane komponente od kojih je sustav sastavljen i postavljeni zahtjevi za upravljanje. Nadalje, odabrani su regulatori koji će se koristiti pri upravljanju temepraturom. Na kraju je sve skupa implementirano i povezano u zajedničku mrežu posredstvom OPC servera. Rezultat je funkcionalan sustav upravljanja temperaturom sastavljen od više komponenti koje međusobno mogu komunicirati, na taj način ispunivši moderne standarde kod implementacije ovakvih sustava.

Abstract (english)

This thesis focus is on regulation and control of temperature in small greenhouse. First, simulation model was made in MATLAB based on laws of heat process dynamics. Various simulations with numerous variables were made, all of wich affected air temeprature. In that way, system components were chosen and rules of temperature regulation were made. Furthermore, air temperature controllers were selected. In the end, all system components were implemented and interconnected through OPC server. The result is functional temperature control system made of various components wich can communicate in real time, in that way fulfilling modern industry implementation standards.
