Abstract
We study a nonlinear model of a biological digestion process, involving two microbial populations and two substrates and producing biogas (methane). A feedback control law for asymptotic stabilization of the closed-loop system is proposed. An extremum seeking algorithm is applied to stabilize the system towards the maximum methane flow rate.
This research has been partially supported by the Bulgarian Science Fund under grant Nr. DO 02–359/2008 and by the bilateral project “Variational Analysis and Applications” between the Bulgarian Academy of Sciences and the Izrael Academy of Sciences.
