✦ Synopsis

The optimization of the operation of biological reactors is an interesting non-linear problem whose solution o!ers potential economic bene"t. We apply a peak seeking method to approach the maximum biomass production rate in a continuous stirred tank bioreactor. Two models, Monod and Haldane, are investigated and it is shown by simulation that the peak seeking scheme achieves optimization for both cases. A stabilizing feedback controller with a washout "lter is designed to extend the operating range for the Haldane model.
