Signal estimation adaptive algorithm with latch-mechanism for real-time water quality monitoring

Year: 2025

Type: article

Abstract: The protection of water reservoirs requires precise monitoring of quality parameters, which is a crucial aspect of water resource management. This article proposes an algorithm for real-time reconstruction of unmeasured signals using only easily accessible measurement data. The proposed method relies on a specially designed latch mechanism and a mathematical river model. The considered river model is described by nonlinear ordinary differential equations derived from a transformation of partial differential equations. The task was accomplished through the application of an adaptive signal estimation algorithm specifically developed for this purpose, with additional tuning of dynamic properties achieved through precise placement of eigenvalues. The results of simulation studies confirmed improved accuracy in reproducing dynamic processes, particularly for signals that are challenging to measure directly, compared to other analysed methods. A practical example of the application of the proposed algorithm is the implementation of a soft sensor to monitor a biochemically polluted river.
