Abstract: This paper exposes and validates a methodology based on a classical hydraulic model (Saint-Venant equations) to design efficient automatic controllers for an irrigation canal pool. The method is applied on a laboratory canal located in Portugal. First, the full nonlinear hydraulic model is calibrated, using a single steady-state experiment, then it is validated on other hydraulic conditions. the control model is obtained by linearizing the Saint-Venant equations and using the linearized models. The experimental results show that such a method is able to accurately predict the closed-loop system behavior in terms of stability, robustness and performance
