Abstract
We study a control problem of delivering water to farmers through an irrigation
canal and introduce a hierarchical controller with a Coordinator that by
employing Model Predictive Control principles coordinates local canal reaches
by modifying setpoints only when it is needed. Once the setpoints are set, the
Coordinator does not interfere with the functioning of the local sites and the
canal is fully controlled by local PI controllers located at each gate.
Therefore the communication between the centralized controller and the local
sites is kept minimal, which is motivated by the communication restrictions
that are present in the field of irrigation. We consider three predictive
control designs, namely a nominal controller, and two robust designs: a
constraint tightening controller adapted to fit our application and a min-max
controller. We present a numerical example to compare the performance obtained
by the three controllers. It is found that for the given case study with a
small disturbance realization, the nominal controller performs better than the
robust controllers, the behaviors of which prove overly conservative.
