Enhanced Adaptive Control of Water Quality in Water Distribution Networks by Incorporating Abrupt Hydraulic Changes

To address the problem of regulating the spatio-temporal distribution of a disinfectant substance, such as chlorine, within a Drinking Water Distribution Network (DWDN), a previous work by Polycarpou et al. (2002) proposed the design of an adaptive controller based on an input-output model of the water quality system. In the present work, an enhanced adaptive water quality control algorithm is presented, which extends the Polycarpou et al. (2002) methodology, by incorporating information regarding planned abrupt hydraulic changes. The improved controller performance due to the proposed enhancement in comparison to previous approaches is demonstrated on a benchmark network.
