Dynamic Optimization for Optimal Control of Water Distribution Systems

摘要

In this paper we consider the design of intelligent control policies for water distribution systems. The controller presented in this paper is based upon a hybrid system that utilizes dynamic programming and rules as design constraints, to minimize average costs over a long time horizon under constraints on operation parameters. The method is very general and is reported here as a controller for a water distribution system. In the example presented we obtain a 12.5 percent reduction in energy usage over the optimal level-based control design. We present the guiding principles used in the design and the results for a simulated system that is representative of a typical water pumping substation. The design is fully adaptable to changing operating conditions and has applicability to a wide range of scheduling problems.
