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 …
In this work, a proportional/integral (PI) material-balance scheme to control continuous free- radical solution homopolymer (possibly open-loop unstable) reactors with level …
T López, J Alvarez - Journal of Process Control, 2004 - Elsevier
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 …
J Alvarez, P González - Journal of Process Control, 2007 - Elsevier
The problem of controlling (possibly open-loop unstable) continuous free-radical solution polymer reactors with temperature, level and flow measurements is addressed. The …
Emulsion copolymerization in semibatch reactors is an industrial process where important commodity and engineering plastics are manufactured, and the design and control of the …
