Abstract
The feedback-induced bifurcation method has been examined as applied to CO oxidation on RhAl 2O 3. Experimental Hopf bifurcation data obtained from operation of the reaction system under feedback control based on measurement of the gas-phase concentration of CO was reproduced by two reaction models. However, a clear distinction between the Hopf bifurcation behavior of the two models was identified when the feedback control was based on the fractional coverage of a surface carbonyl species. Higher-order dynamics resulting from closed-loop operation of the reaction system were also observed. The usefulness of various types of experimental feedback-induced bifurcations as applied to model development is discussed.
