This multiauthor review article aims to bring readers up to date with some of the current
trends in the field of process analytical technology (PAT) by summarizing each aspect of the …

The progressive deterioration of water resources and the large amount of polluted water
generated in industrialized societies gives Wastewater Treatment (WWT) processes a …

The problem of designing a dynamic measurement processor for the on-line estimation of
the state of a multi-input multi-output nonlinear plant is addressed. The plant can be either …

The problem of proving observability/detectability properties for selected non-linear
uncertain model of biochemical processes has been addressed in this paper. In particular …

In this work, a systematic approach based on the geometric observer is proposed to design
a model-based soft sensor, which allows the estimation of quality indexes in a bioreactor …

This article addresses the problem of estimating the state of a multimachine power system
(MPS). To work with power networks with lossy transmission lines, a variation of the classical …

An estimation approach to jointly design the estimation model, data assimilation structure,
and algorithm in the light of particular estimation objectives is developed within a …

This work investigates the design of alternative monitoring tools based on state estimators
for industrial crystallization systems with nucleation, growth, and agglomeration kinetics. The …

A hierarchical extended Kalman filter (EKF) design is proposed to estimate unmeasured
state variables and key kinetic parameters in a first principles model of a continuous …

In this work, the effect of the estimation structure on the performance and robustness
characteristics of a geometric nonlinear estimator is studied for free-radical continuous …
