PREDICTIVE CONTROL WITH CONSTRAINTS OF A MULTI-POOL IRRIGATION CANAL PROTOTYPE

This paper presents a real-time implementation of a multivariable predictive controller with constraints to regulate the downstream levels at the end of the pools in a four-pool open irrigation canal prototype. The objective of the controller is to maintain the downstream level at a constant target value despite inflow disturbances. The controller is designed using a "black box" identified linear model. The results show satisfactory closed-loop performances.
