These Greenhouses should provide a controlled environment for plant production with sufficient sunlight, temperature and humidity. Better growing conditions are achieved in greenhouses mainly by maintaining a higher internal ambient as compared with external temperature. Thus the greenhouse heater requirements depend upon the amount of heat loss from the structure. The proposed scheme measures the on-line sequential data of temperature from the greenhouse and the heating power is recursively updated based on the energy balance of an elementary volume of greenhouse air by using intelligent controllers. Simulation results of the greenhouse dynamics illustrate the effectiveness of the proposed scheme without the exact mathematical model of the plant.
