Abstract
This paper proposes a decentralized model - based predictive controller approach for the design of discrete-time control systems for the regulation of the air temperature and heat supply in greenhouses. A state space model is used at the greenhouse to predict the corresponding indoor temperature over a long-range time period. The sun radiation and outdoor temperature are treated as external disturbances tliat affect the overall system dynamics. A series of energy fluxes consist the heating system and the predictive controllers have proved to be powerful in controlling the supply temperature.
