Bisowarno, Budi H., Tian, Yu-Chu, & Tade, Moses O. (2003) Model gain scheduling control of an ethyl tert-butyl ether reactive distillation column. Industrial and Engineering Chemistry Research, 42(15), 3584 -3591.
Reactive distillation (RD) is a favorable alternative to the conventional series of reaction-separation processes. However, the control of RD is challenging because of its complex dynamics resulting from the integrated functionality of reaction and separation. A linear proportional-integral-derivative algorithm with fixed parameters has been shown not to be satisfactory to handle the high directionality of the process gain. It needs to be retuned adequately over a wide range of operating conditions. In this work, model gain scheduling is investigated for an ethyl tert-butyl ether reactive distillation column. It employs a set of simple local models, which cover relevant operating conditions and cope with the nonlinear characteristics of the process. The simple models are then integrated by using a proper switching scheme. Simulation results have shown that the proposed control strategy outperforms the standard proportional-integral control in both set-point tracking and disturbance rejection.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
