Supervision dynamique d'un canal d'irrigation

Abstract : The main objective of irrigation canals is to satisfy the users' demands on water while preserving water resource. Manual for a long time, canals' control is now automatic which improves water management. Canal automatic control consists on manipulating structures according to measurements of sensors. The good unfolding of control process imposes correct measurements. However in practice, measurements are never correct and are usually subject to random noise and errors. These errors are generally instruments faulty effect. Consequently, it seems important to supply a monitoring system which allows fault detection and isolation.

The work consists in developing a fault detection and isolation method for irrigation canals. This method is based on data reconciliation and diagnosis based observer. The first section concerns the application of data reconciliation on real data of the canal de Gignac. Irrigation canals are time-delay systems. The second section is about the extension of the diagnosis based observer to time-delay systems.
