  1. 1. 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. 2. Transformation and Symbolic Calculations in Filtering and Control

    Författare :Ke Wang-Chen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis deals with several aspects of optimal control and filtering problems. A fundamental problem in the optimal control theory is the design of a regulatorfora linear system which minimizes a quadratic cost function characterizing the control effort and the deviations of the system from the ideal operation.

  4. 3. Cavity Field Control for Linear Particle Accelerators

    Författare :Olof Troeng; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Particle accelerators; Cavity field control; LLRF; Complex-coefficient systems; Q design; Disturbance-rejecting peak filters;

    Sammanfattning : High-energy linear particle accelerators enable exploration of the microscopic structure of pharmaceuticals, solar cells, fuel cells, high-temperature superconductors, and the universe itself. These accelerators accelerate charged particles using oscillating magnetic fields that are confined in metal cavities. LÄS MER

  5. 4. Digital reglering av klimatprocesser

    Författare :Lars Jensen; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uppvärmning; Ventilation; Reglerteknik; Datorstyrning; Digital teknik; Air conditioning; Mathematical models; Experimentation; Temperature control; Humidity control; Computer simulations; uppvärmning; ventilation; reglerteknik; digital teknik; datorstyrning;

    Sammanfattning : Results from a research project supported by the Swedish Council for Building Research are reported. The main task was to improve climate control technology. The work was focused on digital control. It was split up into three main tasks: model building, design of regulators, and fullscale experiments. LÄS MER

  7. 5. System identification in alternative shift operators with applications and some other topics

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

    Sammanfattning : This thesis mainly concentrates on two issues of system identification, namely identification for controller design and identification with orthonormal basis functions. In identification for controller design one seeks to obtain sufficient knowledge about the plant to design a high-performance controller. LÄS MER
