Resumen:
This work deals with the problem of estimation of biomass concentration and specificgrowth rate in a biohydrogen production process. A photo-fermentation process with thephotosynthetic bacteria Rhodobacter capsulatus is considered. The reaction dynamics isrepresented with a Monod law while the hydrogen production rate is modeled witha Luedeking-Piret expression. A sliding mode observer is proposed and designed, whichgives an estimate of both biomass concentration and specific growth rate from measurementsof the produced hydrogen volume. The proposed observer is completely robustagainst the growth kinetic model, and it presents a first-order reduced dynamics.Numerical simulation results are presented for a batch biohydrogen production process.
