Abstract

Tema je ovog rada implementacija sustava za regulaciju temperature u automatiziranom stakleniku. Pomoću poznatih fizikalnih načela napravljen je odgovarajući matematički model sustava. Potom su provedene simulacije korištenjem alata Matlab i Simulink pomoću kojih su odabrane potrebne komponente, kao i optimalni parametri regulatora. Za regulaciju grijanja odabran je PI regulator, dok je upravljanje provjetravanjem i ventilacijom regulirano histerezom. Sustav je implementiran korištenjem analognih ulaza i izlaza PLC-a čime je ostvarena potpuna funkcionalnost za bilo koje vremenske uvjete. Pomoću korisničkog sučelja korisniku su na izbor ostavljeni parametri sustava.

Abstract (english)

This thesis theme is an implementation of temperature control in automated greenhouse. Using laws of Physics, the mathematical model of system was created. Matlab and Simulink were used to make simulations of the system. While adjusting those simulations parameters, optimal system components and parameters were selected. Heating regulation was made using PI regulator, while hysteresis regulators were designed for the cooling system. System was implemented using PLC analog inputs and outputs that secured full system functionality in any weather conditions. Finally, human–machine interface enabled personalized selection of system parameters.
