Experimental evaluation of feedforward tuning rules

This paper presents a practical comparison for some of the most relevant tuning rules feedforward compensators that have been published in recent years. The work is focused on rejection disturbances affect process output. different are evaluated simulation and several performance indices calculated order to provide quantitative comparison. All compared against standard feedback controller classical open-loop design method compensators. Furthermore, two analysed tested real first time. To end, traditional greenhouse was selected as test bed an experimental evaluation controllers context challenging control problem with significant disturbances.
