Optimal Greenhouse Cultivation Control: Quo Vadis?

Worldwide there is a wide variety of greenhouse types en cultivated crops, and consequently control options and control solutions differ. Yet, there are common characteristics that must be considered in every control solution. A versatile framework for greenhouse climate control aiming at economic optimal control is presented. The framework is based on time-scale decomposition. Factors to determine the feasibility of the approach are discussed, as well as options to overcome some of the challenges and issues. The expectation is that with expansion and professionalization of the greenhouse industry the scope for optimal control will become wider.
