BACKGROUND:

Germany has more than 9000 anaerobic digestion (AD) plants in operation, which provide a sustainable source of electricity, heat and substitute natural gas. However, they face economic challenges due to expiring state subsidies. To ensure AD process stability during on-demand operation, novel monitoring and control approaches for AD plants need to be investigated.
Our working group has developed a multirate extended Kalman filter (MR-EKF) that delivered promising results in simulative studies. Moreover, a lab-scale automated feeder at DBFZ allows for dynamic feeding schedules and varying substrates. This thesis aims to demonstrate monitoring of a lab-scale AD process with the MR-EKF and DBFZ’s automated feeder.
As a master’s candidate in our working group, you will be assisted in understanding the underlying process models as well as the methods used to develop code for AD process monitoring on your own. You will thereby gain hands-on experience for your coding skills, solidify your expertise in practical lab work and deepen your knowledge of the AD process.
