Control of an Anaerobic Upflow Fixed Bed Bioreactor

摘要

In this paper the feedback linearization control technique is used for controlling an anaerobic upflow fixed bed reactor, which is used for the degradation of wine distillery waste water. The concentration of the volatile fatty acids is used as the output and the dilution rate is used as the control input. Given the closed loop system to be controlled and the specification for the desired behavior, the control law makes the system to behave correctly. The zero dynamics is found to be stable, guaranteeing that the control technique can be used.
