Simple Water Level Controller for Irrigation and Drainage Canals
Publication: Journal of Irrigation and Drainage Engineering
Volume 125, Issue 4
Abstract
A simple water level controller for irrigation and drainage canals is proposed; the proposed controller has a master-slave structure where the slaves control the flow rates through the control structures. The master controller consists of PI-based controllers for feedback, and a decoupler and feedforward controller that are based on the inversion of a simple dynamic model of the canal system. The applicability of the controller is demonstrated in field experiments.
