TY - JOUR A1 - Raeyatdoost, Niloofar A1 - Eccleston, Robin A1 - Wolf, Christian T1 - Flexible Methane Production Using a Proportional Integral Controller with Simulation‐Based Soft Sensor T2 - Chemical Engineering & Technology N2 - Anaerobic digestion plants have the potential to produce biogas on demand to help balance renewable energy production and energy demand by consumers. A proportional integral (PI) controller is constructed and tuned with a novel tuning method to control biogas production in an optimal manner. In this approach, the proportional part of the controller is a function of the feeding rate and system's degree of stability. To estimate the degree of stability, a simulation‐based soft sensor is developed. By means of the PI controller, the requirement for gas storage capacity of the digester is reduced by approximately 30 % compared to a constant, continuous feeding regime of the digester.
