In industrial processes many key process variables (like conversions, selectivi ties,
concentrations, viscosities etc.) can not be measured adequately (accurately and …

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 …

The extended Kalman filter has been applied to a continuous stirred tank styrene
polymerization reactor for the on-line estimation of state and control of polymer properties …

The extended Kalman filter has been applied to a continuous styrene polymerization
process with mixed initiators for the on-line state estimation and control. Two time scale filter …

The method of Kalman filtering has been used to obtain on-line state estimates of a batch
styrene polymerization reactor. The temperatures of the plant and the refractive index of the …

An experimental and theoretical study has been carried out for on-line estimation and
control of a batch reactor for solution polymerization of methyl methacrylate. The main …

The issue of parameter estimation in Extended Kalman Filters is addressed in this paper. It is
shown that the use of parameters as additional system states is appropriate whenever there …

In this paper, we describe and present results from the online, real time implementation of
polymer property estimation techniques for an industrial polymerization reactor. We use …

In the paper the control of the product quality in polymerization reactors is analysed in the
presence of persistent perturbations (unmodeled disturbances, modeling errors), as met in …

The aim of this work is the development and implementation of industry-relevant model-
based estimation and control algorithms for complex chemical processes. One of the major …
