Reglering av sackaroshalten vid fermentation i en reaktor med kontinuerligt flöde
(1982) In MSc ThesesDepartment of Automatic Control
- Abstract
- Fermentation in a 5 l continuous flow reactor with immobilized yeastcells is controlled. Substrate concentration (sucrose) is continuosly measured with an enzyme thermistor. The control variable is flowrate through the reactor. The main controlproblem is a timelag in the measurementsignal. A bilinear processmodel is formulated and used for design of different controllers. Comparison is done between conventional PID-, Otto-Smith-PI-regulator, state-feedback from Kalmanfilter and regulator based on polynomsynthesis. Controllers are tested in simulation and on the real process. Implementation is done on a PDP-11 computer. Programs are written in PASCAL extended with a realtime kernel.
