Optimal control of fructo-oligosaccharide production

摘要

The objective of this study is to determine an optimal substrate feed rate for optimizing the fructo-oligosaccharide production by Aureobasidium pullulans in a fed batch reactor. The feed profile is charecterized by the feed start time, rate and end time. The optimization is carried out based on a simple dynamic model of the process and using Pontryagin maximum principle in the framework of singular control problems. The resulting control law is of the bang-bang type. The bioreactor is first filled-up at maximum feed rate, followed by a batch phase.
