Optimal control of nonlinear groundwater hydraulics using differential dynamic programming

摘要: Optimal groundwater management models are based on the hydraulic equations of aquifer system. These relate state variables system, head, and decision that control magnitude, location, timing pumping, or artificial recharge. For unconfined these large-scale, nonlinear programming problems. A differential dynamic (DDP) algorithm is used for unsteady, nonlinear, Due to stagewise decomposition DDP, dimensionality problems associated with embedding as constraints in model significantly reduced. In addition, DDP shows a linear growth computing effort respect number stages planning periods, quadratic convergence. Several example illustrate application optimal hydraulics.
