Description
Summary:Results of analysis and design and implementation of a temperature controlsystem for a practical pilot anaerobic digestion (AD) bioreactor fed with dairywaste are presented. A dynamic model of the reactor temperature is used asthe basis for theoretical results, including simulations. Controller functionsinclude on-off control, proportional plus integral (PI) control, andfeedforward control. Various PI controller tuning methods are compared. Theneed for adaptivity of PI settings is investigated. Results for asimulated full-scale reactor are given.
