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 …

In this work the problem of designing a state estimator for completely or partially observable
continuous nonlinear plants with discrete measurements is addressed. The combination of a …

An on‐line state‐estimation design for multiinput multioutput nonlinear plants, either
observable or detectable, is presented. The design considers a stage of analysis, in which …

A large number of high activity catalysts are used to produce different grades of polymers in
a continuous olefin polymerization reactor. Often the transition from one grade to another is …

An integrodifferential estimation approach is applied to draw the reactivity ratio (RR)
dependencies on the monomer feed composition. The approach combines the integral …

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 …

The research addressed in this paper is focused on the estimation and control of a nonlinear
industrial polymerization process. The majority of the available estimation techniques are …

The validity of an online state estimator for a semi‐batch MMA/MA solution copolymerization
reactor was established using online densitometer and viscometer. Using the conventional …

Polymer reactor control problems often lack frequent measurements of polymer properties,
while other reactor environment measurements, such as temperatures, are readily available …

State estimation from plant measurements plays an important role in advanced monitoring
and control technologies, especially for chemical processes with nonlinear dynamics and …
