Autor: RM Pilatti, TQ Furian, DA Lima, F Finkler, BG Brito, CTP Salle, HLS Moraes
Publikováno v: Brazilian Journal of Poultry Science, Vol 18, Iss 2, Pp 255-260
ABSTRACT Although Pasteurella multocida is a member of the respiratory microbiota, under some circumstances, it is a primary agent of diseases , such as fowl cholera (FC), that cause significant economic losses. Experimental inoculations can be emplo

Gray-Box system modeling using symbolic regression and nonlinear model predictive control of a semibatch polymerization
Autor: Uwe Piechottka, Lukas Scheffold, Tiago F. Finkler
Publikováno v: Computers & Chemical Engineering. 146:107204
A nonlinear model, predictive control approach, based on a gray-box model is introduced in this contribution. The gray-box model is built by combining white-box and black-box modeling elements. The white-box elements consist of relevant mass and ener

Realization of Online Optimizing Control in an Industrial Polymerization Reactor
Autor: Tiago F. Finkler, Sebastian Engell, Uwe Piechottka, Michael Kawohl
Publikováno v: IFAC Proceedings Volumes. 45:11-18
In this work, the operation of an industrial semi-batch polymerization reactor is economically optimized using an NMPC scheme. The goal is the minimization of the batch duration without violating the tight constraints for the product specification. I

Scheme for Time-optimal Operation of Semi-batch Emulsion Polymerization Reactors
Autor: Tiago F. Finkler, Heiko Brandt, Katja Pelz, Sebastian Engell
Publikováno v: IFAC Proceedings Volumes. 45:239-244
Emulsion polymerization processes are characterized by exothermic reactions with complicated nonlinear dynamics. A very precise temperature control is necessary in order to ensure that the end product satisfies the quality demands. In industry, this
