Control Node Placement and Structural Controllability of Water Quality Dynamics in Drinking Networks
Salma M. Elsherif, Ahmad F. Taha
Chlorine, the most widely used disinfectant, needs to be adequately distributed in water distribution networks (WDNs) to maintain consistent residual levels and ensure safe water.…
Climate Science and Control Engineering: Insights, Parallels, and Connections
Salma M. Elsherif, Ahmad F. Taha
Climate science is the multidisciplinary field that studies the Earth's climate and its evolution. At the very core of climate science are indispensable climate models that predict…
Observability and Generalized Sensor Placement for Nonlinear Quality Models in Drinking Water Networks
Mohamad H. Kazma, Salma M. Elsherif, Ahmad F. Taha
This paper studies the problem of optimal placement of water quality (WQ) sensors in water distribution networks (WDNs), with a focus on chlorine transport, decay, and reaction mod…
Quality-Aware Hydraulic Control in Drinking Water Networks via Controllability Proxies
Salma M. Elsherif, Mohamad H. Kazma, Ahmad F. Taha
The operation of water distribution networks simply aims at efficiently delivering consumers adequate water while maintaining safe water quality (WQ). However, this process entails…
Disinfectant Control in Drinking Water Networks: Integrating Advection-Dispersion-Reaction Models and Byproduct Constraints
Salma M. Elsherif, Ahmad F. Taha, Ahmed A. Abokifa
Effective disinfection is essential for maintaining water quality standards in distribution networks. Chlorination, as the most used technique, ensures safe water by maintaining su…
