Abstract
Proposes efficient bicarbonate control strategies for anaerobic digestion processes. The bicarbonate concentration which is easier and cheaper to measure than volatile acids concentration is regulated in order to stabilize the process. Adaptive linearizing and L/A control strategies using as control input either the dilution rate or the influent bicarbonate are proposed. The controllability properties of both inputs for the assumed nonlinear mathematical model are analyzed through linearization around steady-states. Simulations results are presented and discussed.
