OPTIMAL-CONTROL OF WATER-SUPPLY PUMPING SYSTEMS

The requirements and basic components of a typical optimal control env ironment for water-supply pumping systems are presented and discussed. Examined model components include hydraulic network models, demand fo recast models, and optimal control models. A review of existing optima l control methodologies for water-supply pumping systems is also provi ded. Examined methodologies are classified on the basis of the type of system to which the methodology can be applied (single source-single tank or multiple source-multiple tank), the type of hydraulic model us ed (mass balance, regression, or hydraulic simulation), the type of de mand model used (distributed or proportional), the type of optimizatio n method used (linear programming, dynamic programming, or nonlinear p rogramming), and the nature of the resulting control policy (implicit or explicit). Advantages and disadvantages of each approach are presen ted, along with recommendations for future work. The applicability of current technology to an existing water-supply pumping system is exami ned in light of existing technical limitations and operator acceptance issues.
