  3. 7. Towards Improved Control of TMP Refining Processes

    Författare :Karin Eriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control; dynamic modeling; process limitations; simplified decoupling; Refiner; refining zone temperature; internal interconnections;

    Sammanfattning : The need for improved energy usage has become a key issue in all industrial sectors. In the energy demanding production of mechanical pulps many efforts havefocused on design development, but regarding control of refiners, there is still a potential for improvements. LÄS MER

  4. 8. Probing Control : Analysis and Design with Application to Fed-Batch Bioreactors

    Författare :Stéphane Velut; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; Large scale fermentations; Extremum control; Feeding strategy; Probing control; Fed-batch bioreactors; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : In most control problems the objective is to control the output at a desired value in spite of disturbances. In some cases, the best setpoint is not known a priori and it should be found online to optimize the process performance. This thesis examines a probing strategy that can be applied for this class of problems. LÄS MER

  5. 9. Learning control for flex-fuel CI engine and fuel cell

    Författare :Xiufei Li; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flex-fuel CI Engine; Fuel Cell; Model Predictive Control; Learning Control; Adaptive Control; Gas System Model; Ignition Delay Model; Data-based Modeling; Gaussian process;

    Sammanfattning : This thesis investigated the modeling and control problems in the context of the flex-fuel compression-ignition (CI) engine and fuel cell, which shows great potential in the transition from fossil fuel to renewable energy sources.The modeling parts included the flex-fuel engine combustion process and intake system, and the system scale fuel cell model.
