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 …

The difficulties encountered in chemical engineering arise from the lack of reliable and
robust sensors. Several works deal with the design of software sensors in order to estimate …

Polymerization processes require adequate monitoring to ensure that the final product
meets specification. Various on-line measuring techniques have been developed and …

This paper concerns nonlinear state estimation in a continuous polymerization reactor
where free-radical solution polymerization of methyl methacrylate takes place. Initiator and …

In this article, the problem of observer design in linear multi‐output systems with
asynchronous sampling is addressed. The proposed multi‐rate observer is based on a …

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 …

The control of polymerization processes has central importance because operational
conditions affect the processing and end-use properties of the product. The nonlinear …

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