Biomass Estimation for an Anaerobic Bioprocess Using Interval Observer

  • Elena M. Bunciu
Part of the Smart Innovation, Systems and Technologies book series (SIST, volume 10)


This work deals with the analysis of an anaerobic digestion process model and its biomass estimation using an interval observer. In this paper a two step mass balance model is presented. Due the fact that we don’t know the influent substrate, as quantity or shape, but we know its upper and lower limit, we can estimate the quantity of biomass only by using an interval observer. As we know, this two step model has incorporated electrochemical equilibrium, for including the alkalinity that helps to a better control strategy of the plant in which the reactions are taken place.
