Climate control techniques in greenhouses are to improve plants requirements and prevent unnecessary power consumption. Several parameters may affect the growing of plants: internal air temperature, inside vapor pressure and Co2 concentration. The equilibrium of these settings is obtained by choosing the appropriate monitoring actions. Here we developed a dynamic and complex nonlinear coupled (MIMO) system of a horticultural greenhouse by using the MATLAB/SIMULINK environment. In this paper the most widely used proportional -integral (PI) controller was compared to the new integral -proportional (IP) controller.
