Feedforward controllers for greenhouse climate control based on physical models

This paper presents the development of feedforward controllers for greenhouse climate control. These controllers are mainly based on physical laws and measured data and are discussed in terms of their suitability for disturbances cancellation and potential use for adaptive control purposes. The schemes are tested using a nonlinear model of a typical Mediterranean greenhouse previously developed by the authors and some results and conclusions are included in the paper that show the benefits of the use of feedforward controllers for disturbance cancellation.
