Model-based control strategies for anaerobic digestion processes

Neli Dimitrova, Mikhail Krastanov


In this paper we consider a four-dimensional bioreactor model, describing an anaerobic wastewater treatment with methane production. Different control strategies for stabilizing the dynamics are presented and discussed. A general and practice-oriented bounded open-loop control is proposed, aimed to steer the model solutions towards an a priori given set in the
phase plane.
