[en] In this note, we design an invariant observer for a two step (acidogenesis-methanogenesis) mass balance nonlinear model, in order to estimate simultaneously all bacteria and substrate concentrations found in the anaerobic digestion process. The particularity of the designed observer is the use of only the methane flow rate which is cheap to measure and commonly measured online even at industrial scale.
