We introduce an asymptotic observer of constant gain for nonlinear systems that have linear input. This allows the observer design to be formulated within the linear matrix inequality paradigm provided that a strictly positive real condition between the input disturbance and the output is fulfilled. The proposed observer is then applied to a large class of nonlinear Chemostat dynamical systems that are widely used in the fermentation process, cell cultures, medicine, etc. In fact, under standard practical assumptions, the necessary change of the Chemostat state coordinates exists, allowing use of the constant gain observer. Finally, the developed theory is illustrated by estimating pollutant concentration in a Spirulina maxima wastewater treatment\nfacility. reportyear 2022 RIV BC result_subspec WOS FORD0 20000 FORD1 20200 FORD2 20205 num_of_auth 4 mrcbC52 4 A sml 4as 20231122145216.6 inst_support RVO:67985556 permalink http://hdl.handle.net/11104/0312001 cooperation ARLID cav_un_auth*0398287 name Automatic Control Department, CINVESTAV, Mexico City institution ACD, Cinvestav country MX cooperation ARLID cav_un_auth*0398288 name Biotechnology and Bioengineering Department, CINVESTAV, Mexico City institution BBD, Cinvestav country MX confidential S contract name Copyright Transfer Statement date 20200921 mrcbC86 3+4 Article Computer Science Information Systems|Computer Science Software Engineering|Engineering Electrical Electronic mrcbC91 C mrcbT16-e COMPUTERSCIENCEINFORMATIONSYSTEMS|COMPUTERSCIENCESOFTWAREENGINEERING|ENGINEERINGELECTRICALELECTRONIC mrcbT16-j 0.487 mrcbT16-s 0.733 mrcbT16-D Q3 mrcbT16-E Q2 arlyear 2021 mrcbTft \nSoubory v repozitáři: celikovsky-0533650-Copyright_ Transfer_Statement-2.pdf mrcbU14 85100503079 SCOPUS mrcbU24 PUBMED mrcbU34 000609181400006 WOS mrcbU63 cav_un_epca*0475466 Frontiers of Information Technology & Electronic Engineering 2095-9184 2095-9230 Roč. 22 č. 1 2021 68 78 Zheijiang University Press
