Seshu Kumar Damarla, Madhusree Kundu . Control of Yeast Fermentation Bioreactor in Subspace. International Journal of Computer Applications. 64, 5 ( February 2013), 13-20. DOI=10.5120/10629-5357
PCA based temperature controller was used to control Ethanol concentration produced in Yeast fermentation process. The controller was designed at a specific operating point and its disturbance rejection performances were studied. Substrate inlet temperature proved to be the most significant disturbance input from the analysis of open loop responses. Q-statistic (SPE) of process measurements confirmed that in the face of disturbances and noise the process could be held to the specific operating condition using the controller designed in subspace.
