Nonlinear model predictive controller for water wasting reduction in open-channel irrigation systems
In open-channel irrigation systems (OCIS), most of the water is lost by seepage and leaks. However, the reported control strategies for OCIS are not focused on leaks and seepage minimization.

| Resumo: | In open-channel irrigation systems (OCIS), most of the water is lost by seepage and leaks. However, the reported control strategies for OCIS are not focused on leaks and seepage minimization. Therefore, aiming to contribute to the reduction of waste of water, in this paper, an efficient control approach for OCIS, capable to reduce the waste of water by up to 50%, is presented. The proposed strategy is a nonlinear model predictive control that operates under request mode, which has been designed using a simplified modeling approach capable to describe the behavior of the OCIS along a broad operation region. The proposed strategy has been tested using a well-known test bed of the literature, and the results show that, by using this strategy, an appropriate amount of water can be supplied to the users, and the waste of water can be significantly reduced. |
