Abstract: A new class of downstream water-level feedback controllers is proposed that can vary from a series of individual proportional-integral (PI) controllers (each gate adjusted based on one water level) to fully centralized ...

Abstract: The operation of a new irrigation canal system in central Arizona is described. Water is relatively expensive, and thus farmers pressure the irrigation district to improve delivery service and keep water losses to a minimum. ...

Abstract: Over the past two decades, numerous automatic control systems have been proposed for irrigation canal operation. Types of automatic control systems range from empirically based, for a one-canal pool, to multivariable ...

Abstract: This paper presents a water-level control system for the Meuse river, the implementation of which is planned to start in 1997. A simplified model is used for the tuning of and design of the controllers. To obtain a highly ...

Abstract: Schuurmans et al. (1995a) presented a model for the design of water level controllers for irrigation and drainage canals that describes the essential characteristics of the processes relevant for canal control (such as ...

Abstract: Canals or open channels that convey water often consist of pools in series separated by control structures. Successful implementation of water-level control with these structures using decentralized proportional integral ...

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 ...
