Development of advanced and practice oriented control concepts for biogas plants

In order to maximise the energy production of biogas plants, it is necessary to achieve a high utilisation rate of the energy input (biomass) of e.g. 90%. Up to now only a 70% utilisation rate is reached. In this project, a model based predictive controller was developed. This controller is based on the new NIRS sensors and an innovative model of the substrate transport in the reactor.
