Biogas is a well-established renewable energy source produced from anaerobic digestion
(AD) of biomass/feedstock. It is probably the most versatile and efficient biofuel in terms of …

When treating municipal wastewater, the disposal of sludge is a problem of growing
importance, representing up to 50% of the current operating costs of a wastewater treatment …

In this paper, we present a new systematic method to design observer-based tracking
control for a class of linear parameter varying (LPV) systems in the presence of Lipschitz …

Anaerobic digester failure due to entry of inhibitors or sudden changes in the feed substrate
concentration may be encompassed beneficially by applying optimal control theory. An …

A dynamical output feedback control for the regulation of the chemical oxygen demand
(COD) in anaerobic digestion is discussed in this paper. The control law can have different …

The design and implementation of a new adaptive controller for anaerobic digesters is
presented using a general nonlinear model and an uncertainties estimation scheme. The …

The association of a wall growth factor with a dynamic model based on Andrews' work
(1969), without pH restrictions, is used herein to study the inhibition of methanogenesis by …

In this work a robust control strategy is proposed to regulate the chemical oxygen demand
(COD) in an anaerobic digestion process. The proposed strategy is a dynamical output …

ABSTRACT A biological dynamic model for the methanogenic phase of an anaerobic
digester with and without wall growth factor is developed for the substrate and …

This chapter deals with the design of observer-based control strategies via linear matrix
inequalities (LMIs) for the anaerobic digestion (AD) process. The purpose is to track state …
