This paper is devoted to the tuning problem of an observer-based algor
ithm for the on-line estimation of reaction rates in stirred tank bior
eactors. The relation between the dynamics of convergence and the tuni
ng procedure is explored. The method proposed imposes a variable secon
d-order dynamics on the convergence of the estimator. This approach is
shown to compare favourably with a pole placement based technique, in
an application to a baker's yeast fed-batch fermentation. Copyright (
