Optimal Control Design for a Solar Greenhouse

An optimal climate control has been designed for a solar greenhouse to achieve optimal crop production with sustainable instead of fossil energy. The solar greenhouse extends a conventional greenhouse with an improved roof cover, ventilation with heat recovery, a heat pump, a heat exchanger and an aquifer.It was found that in the optimal controlled solar greenhouse, gas use can be seriously reduced (by 52%), while the crop production is significantly increased (by 39%), as compared to an optimal controlled conventional greenhouse without the solar greenhouse elements.
