Abstract
.This paper presents the application of the photovoltaic energy to supply electrical power for a temperature controlling system of a greenhouse. A linearizing algorithm is applied to the physical model of the greenhouse in order to calculate the needed air flow to cool down the temperature if it exceeds a wanted level. The control of the temperature is ensured by a fan ventilation system through a DC/AC converter and an asynchronous machine.
The model of the PV system and the greenhouse has been implemented in the Matlab/Simulink software and simulations have been presented to show the efficiency of the proposed system.
