A Gain-scheduling Approach for Control of Dissolved Oxygen in Stirred Bioreactors

Åkesson, Mats LU and Hagander, Per LU (1999) 14th IFAC World Congress (1999)
Abstract
This paper discusses control of dissolved oxygen in a bioreactor when the stirrer speed is used as control signal. During batch and fed-batch cultivations the operating conditions change significantly which causes tuning problems, especially when performance requirements are high. A linearized process model reveals that the variations in the oxygen dynamics are mainly due to changes in the volumetric oxygen transfer coefficient $K_La$.
