Robust Temperature Regulation in Chemical Reactors with Unknown Reaction Rates

摘要

In this work we study the stabilization of continuous stirred tank reactor with unknown reaction rates. We prove that, under certain general assumptions, the chemical reactor can be stabilized with a high-gain feedback. Simulations shows that high-gain feedback may lead to hard input saturation and poor closed-loop performance. A reaction rate uncertanty estimator is introduced wich, when coupled with anon-linear feedback, .leads global stability with acceptable conrol performance. We conclude state obsevation is unnecessary for the stabilization of the class of chemical reactors here considered.
