Identification and control of an open-flow canal using LPV models

In this paper, the identification and control of open-flow canals using linear parameter varying (LPV) models is proposed. A single reach open-flow canal has been modeled with an LPV first-order plus delay model relating upstream and downstream flows. The parameters of such model depend on the operating point and have been estimated using a parameter estimation algorithm for LPV models. The control is based on a gain-scheduling PI controller with a delay-scheduling Smith Predictor. Finally, the proposed LPV model, identification and control algorithms have been applied to a simulated open-canal: the Lunax gallery located at Gascogne (France).
