Anaerobic digestion (AD) is a highly nonlinear time‐varying process commonly used for
biological wastewater treatment, which is subject to large disturbances of both influent …

We consider the problem of global stabilization of an unstable bioreactor model (eg, for
anaerobic digestion), when the measurements are discrete and in finite number …

The saturated OF control problem for a class of four-state anaerobic digesters with volatile
fatty acids (VFAs) measurement is addressed. The reactor must operate about an optimal …

In recent years manure-based biogas plants (MBBP) have won more and more importance,
because of the numerous ecological advantages. The processes are similar to processes …

In this work, an experimental implementation of a model based output feedback (OF)
scheme applied to regulate the volatile fatty acids concentration of an anaerobic digestion …

A robust state estimation scheme is proposed for anaerobic digestion (AD) processes to
estimate key variables under the most uncertain scenarios (namely, uncertainties on the …

Abstract pH measurements taken from anaerobic digestion (AD) processes show
fluctuations with an apparent random behavior that is usually associated to noise. However …

Although anaerobic digestion is a widely applied technology, the process is not yet fully
understood because of its high complexity, and an optimization of the current technology is …

Efficient monitoring and control of anaerobic digestion (AD) processes are necessary in
order to enhance biogas plant performance. The aim of monitoring and controlling the …

The European Union (EU) has set a goal that 20% of the gross final energy consumption in
the EU should be produced by renewable energy sources in the year 2020 (Holm-Nielsen et …
