Abstract
As energy costs are one of the main production costs many efforts were made to reduce the energy consumption of greenhouses. One possibility is the development of new control strategies. The cascade control system of the greenhouse is investigated. The external loop is organized on the base of air temperature controller. For the compensation of „fast" disturbances (solar radiation, wind speed) the control of water flowrate through the hot-water system in the dependence of the signal proportional to disturabances is realized Also predictive control law is used.
