Greenhouse Temperature Control System

Abstract

This paper proposes to control the temperature regime in the greenhouse using the universal controller OWEN TPM 151. The tuning controller was performed using the maximal stability degree method. As a result of this study, the algorithm of tuning controllers and the procedure of determining the system’s performance in dependence of maximal stability value are proposed. The control object was identified using the System Identification Toolbox from MATLAB. The obtained results were compared with results obtained using the auto-tune regime from OWEN TPM 151 controller.
