INTERVAL ASYMPTOTIC ESTIMATOR FOR CHLORINE MONITORING IN DRINKING WATER DISTRIBUTION SYSTEMS

Asymptotic and interval observer for quality monitoring in drinking water distribution systems is derived in this paper. It produces robust interval bounds on the estimated state variables of the water quality. Solving two differential equations generates the bounds; hence the numerical efficiency is sufficient for on-line monitoring of the water quality. The observer is applied to example water network and tight bounds-estimates are obtained.
