Unknown Inputs and Reaction Rates Estimation in a CSTR with Full Concentration Vector Measurement

Year: 2025

Type: article

Abstract: We address the problem of estimating the instantaneous reaction rates of the mass conversion taking place in an isothermal and isobaric continuous stirred tank reactor, CSTR, subject to a constant dilution rate. In addition to the estimation of the reaction rates, we also obtain an estimate of the influxes to the reactor. Our methodology requires the knowledge of the stoichiometric matrix and all the concentrations online, as well as the dilution rate. The observer is based on a generalised version of the Super-Twisting Algorithm, STA, which allows us to estimate in finite-time the unmeasured variables. The applicability of the observer is shown by a numerical simulation.
