  1. 16. Experiment design with applications in identification for control

    Författare :Henrik Jansson; Håkan Hjalmarsson; Paul von den Hof; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; electronics engineering; electrical engineering; Reglerteknik; Automatic control; Reglerteknik;

    Sammanfattning : The main part of this thesis focuses on optimal experiment design for system identification within the prediction error framework. A rather flexible framework for translating optimal experiment design into tractable convex programs is presented. The design variables are the spectral properties of the external excitations.

  3. 17. Selection of Decentralized Control Configuration for Uncertain Systems

    Författare :Ali Kadhim; Wolfgang Birk; Thomas Gustafsson; Miguel Castaño Arranz; Torsten Wik; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : Industrial processes nowadays involve hundreds or more of variables to be maintained within predefined ranges to achieve the production demands. However, the lack of accurate models and practical tools to design controllers for such large processes motivate the engineers/practitioners to break the processes down into smaller subsystems and applying decentralized controllers.

  4. 18. Model-based control and monitoring of the flotation process

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

    Sammanfattning : In the mineral processing industry, flotation constitutes the most important technique for extraction of the valuable minerals from the ore. This process involves both chemical and physical parts, the theory of which are not yet completely understood. LÄS MER

  5. 19. On-Line Structure Selection for the Identification of Multivariable Systems

    Författare :A J M van Overbeek; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-line structure; Identification; Multivariable systems;

    Sammanfattning : An algorithm is described for the selection of mod el structure for identifying multivariable mode Is of"black box" character. The algorithm receives as "input" a mode I in a given parametrization (= mode I structure). It is then tested whether this parametrization is suitable (well conditioned) for identification purposes.

  7. 20. On the control of systems with input saturation or periodic disturbances

    Författare :Kirthi Sarachchandra Walgama; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : This thesis deals with two important problems in control theory and practice. The first problem is the windup problem in controllers where there exist non-linearities between the controller output and the process input. LÄS MER
