  1. 16. On Model Libraries for Thermo-hydraulic Applications

    Författare :Jonas Eborn; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling; simulation; Matematik; Automation; Termisk teknik; control systems; nonlinear models; parameter estimation; proces s control; thermo-hydraulic systems; model validation; Thermal engineering; applied thermodynamics; termodynamik; Automatiska system; robotics; control engineering; reglerteknik; robotteknik; Mathematics; object-oriented;

    Sammanfattning : Mathematical modelling and simulation are important tools when dealing with engineering systems that today are becoming increasingly more complex. Tightly integrated production and process optimization are trends that give rise to heterogeneous systems, which are difficult to handle without expertise in several engineering disciplines. LÄS MER

  3. 17. 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. 18. Control Strategies for Machining with Industrial Robots

    Författare :Olof Sörnmo; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Robots; Machining; Control;

    Sammanfattning : This thesis presents methods for improving machining with industrial robots using control, with focus on increasing positioning accuracy and controlling feed rate. The strong process forces arising during high-speed machining operations, combined with the limited stiffness of industrial robots, have hampered the usage of industrial robots in high-end machining tasks.

  5. 19. Styrning av organisationer : ett systemperspektiv tillämpat på statliga företag

    Författare :Carin Holmquist; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; inter-organizational relations; control relations; state enterprise; actors perspective; complexity; uncertainty; game of power; Företag; Statlig verksamhet; Företagsledning; Business studies; Företagsekonomi; företagsekonomi; Business Studies;

    Sammanfattning : This is a study of inter-organizational relations, especially of control relations, applied to Swedish state enterprise.The growing interdependence between different parts of society as well as the dynamic environment of organizations bring forward a need for new patterns of interaction.

  7. 20. Optimal Control of Electric Bus Lines

    Författare :Rémi Lacombe; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eco-driving; Electric buses; Bus bunching; Nonlinear programming; Optimal control; Model predictive control;

    Sammanfattning : Bus lines are inherently unstable systems, where any delay tends to be further amplified by the accrued passenger loads encountered at stops downstream. This self-reinforcing mechanism, when combined with the multiple sources of disturbances of an urban environment, can lead to the problem of bus bunching. LÄS MER
