Modeling, Control and Optimization of a Plate Reactor
… with the efficient mixing and reaction control typical of microreactors. With this new concept, highly exothermic reactions can be produced using more concentrated reactants and more accurate temperature control. This will reduce the reaction time and the need for downstream separation, …

Perturbation-based Control of Industrial Fed-batch Bioprocesses
The topic of this thesis is bioprocess control, more specifically control of industrial-scale microbial fed-batch bioprocesses. Its focus is therefore on methods which are easy to implement in an industrial setting, which gives certain limitations on sensors, actuators and control systems. The main …

Control Structures for Low-Emission Combustion in Multi-Cylinder Engines
… predictable and inherently more difficult to control. This thesis summarizes work on control structures for three different setups of such low-emissions combustion engines. In a port-fuel injection engine, it was shown that combining two control variables in a mid-ranging control structure can …

Modeling and Control of the Open Plate Reactor
The focus of this thesis is on modeling and control of the Open Plate Reactor (OPR), a new heat exchange reactor being developed by Alfa Laval AB. It combines intensified mixing with enhanced heat transfer capacity into one operation. With the novel concept, highly exothermic reactions can be …

Feeding Strategies Based on Probing Control for E. coli and V. cholerae Cultivations
… The effect on the tuning rules of the probing controller is investigated. The probing feeding strategy is further improved for a more efficient product synthesis. This new fermentation technique manipulates the temperature when the maximum oxygen transfer capacity of the reactor is reached. The …

Modeling and Control of the Paper Machine Drying Section
The topic of this thesis is modeling and control of the last part of the paper machine - the drying section. Paper is dried by letting it pass through a series of steam heated cylinders and the evaporation is thus powered by the latent heat of vaporization of the steam. The moisture in the paper is …
