Multi-stage model predictive control of agricultural anaerobic digestion plant with uncertain substrate characterization Open
Revenues of anaerobic digestion (AD) plants can be increased by generating biogas and electricity on demand or through biogas upgrading. However, suitable control procedures for individual applications are required to guarantee optimal pro…

Comparison of Unscented Kalman Filter Design for Agricultural Anaerobic Digestion Model Open
Dynamic operation of biological processes, such as anaerobic digestion (AD), requires reliable process monitoring to guarantee stable operating conditions at all times. Unscented Kalman filters (UKF) are an established tool for nonlinear s…

Observability and Identifiability Analyses of Process Models for Agricultural Anaerobic Digestion Plants Open
Dynamic operation of anaerobic digestion plants requires advanced process monitoring and control. Different simplifications of the Anaerobic Digestion Model No. 1 (ADM1) have been proposed recently, which appear promising for model-based p…
