nonlinear programming and irrigation
|Journal:||AIP Conference Proceedings|
|Abstract(s):||A model to optimize the water use in the irrigation of a farm ﬁeld via optimal control (water ﬂow) that take into account the evapotranspiration, rainfall, and losses by ﬁltration and runoff was developed in . Here we improve the previous model to take into account real data of rainfall. Model predictive control is applied to replan. We test and compare different nonlinear constrained optimization techniques for solving the nonlinear constrained optimization problem that arises from the discretization of the proposed optimal control problem. Furthermore, we test different time discretization steps.|
