This paper presents the implementation, calibration and validation of a water model that can be used both for simulation and prediction purposes within a control strategy aimed at determining the ideal irrigation schedule (quantity and frequency) for crop growth in greenhouse using rockwool substrate. One of the main advantages of the model is that model-based irrigation can be performed using online measurements obtained from a relative water content in the substrate sensor as feedback signals, instead of irrigating only using the users’ experience or other kind of (expensive) ...
