Optimum-Seeking by Feedback For Bioreactor Models

摘要

The optimization of the operation of biological reactors is an interesting nonlinear problem whosesolution offers potential economic benefit. We apply a peak seeking method to approach themaximum biomass production rate in a continuous stirred tank bioreactor. Two models, Monod andHaldane, are investigated and it is shown by simulation that the peak seeking scheme achievesoptimization for both cases. A stabilizing feedback controller with a washout filter is designed toextend the operating range for the Haldane model.
