In this work, a novel controller is proposed in order to regulate the dynamic behavior of a class of continuous bioreactor for biogenic hydrogen production, the closed-loop performance of the considered bioreactor increase considerably the hydrogen production successfully. A mathematical model for the anaerobic fermentation of the non-sulfur bacteria Rhodobacter capsulatus is considered as a benchmark system to implementing the proposed methodology. A theoretical sketch of proof of the asymptotic closed-loop stability of the proposed controller is given, considering that the main nonlinearities of the bioreactor's model are bounded. Numerical experiments were carried out in order to show the satisfactory performance of the proposed controller in comparison with an adequately tuned linear PI control law.
