  2. 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

  3. 8. On repetitive control

    Författare :Gunnar Hillerström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : This thesis will concern control systems ability to enhance performance by repeating, while maintaining a stable and sufficiently fast closed loop performance. Iterative techniques can be divided into repetitive and learning control. LÄS MER

  4. 9. Integer Quadratic Programming for Control and Communication

    Författare :Daniel Axehill; Anders Hansson; Manfred Morari; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integer Quadratic Programming; Model Predictive Control; Hybrid Systems; Semidefinite Programming; Code Division Multiple Access; Multiuser Detection; Automatic Control; Communication; Automatic control; Reglerteknik;

    Sammanfattning : The main topic of this thesis is integer quadratic programming with applications to problems arising in the areas of automatic control and communication. One of the most widespread modern control methods is Model Predictive Control (MPC). In each sampling time, MPC requires the solution of a Quadratic Programming (QP) problem. LÄS MER

  5. 10. Management Control : Linking Strategy with Inter‐Organisational Relationships

    Författare :Zita Ambrutytė; Jonas Gerdin; Linköpings universitet; []
    Nyckelord :Management control systems; business strategy; inter-organisational relationships; management control variables; intra-organisational controls; Management control systems; styrsystem; affärsstrategi; inter-organisatoriska relationer; styrvariabler; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : The alignment of strategies and control systems is believed to affect the chances for firms to successfully achieve competitive edge. Contemporary business trends like globalization, vertical disintegration, the reduction in supplier bases, the focusing of operations and outsourcing of non-core activities, have caused companies to rely increasingly on relationships with other firms.
