  1. 1. Digital reglering av klimatprocesser

    Författare :Lars Jensen; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  2. 2. Minimum-time sliding mode control of robot manipulators

    Författare :Boyko Iliev; Ivan Kalaykov; Krzysztof Kozlowski; Örebro universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; minimum-time sliding mode control; sliding mode control; maximum-slope sliding lines; Takagi-Sugeno fuzzy systems; robot manipulators; reglerteknik; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

    Sammanfattning : Robot manipulators have a complex and highly nonlinear dynamics, accompanied with a high degree of uncertainty. These properties make them difficult for time-optimal control. The theory of sliding mode control can provide methods, able to cope with the uncertainty and nonlinearity in the system. LÄS MER

  3. 3. Underactuated mechanical systems : Contributions to trajectory planning, analysis, and control

    Författare :Pedro La Hera; Anton Shiriaev; Ambarish Goswami; Umeå universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underactuated mechanical systems; mechanical systems with impacts; trajectory planning; periodic trajectories; orbital stabilization; walking robots; virtual holonomic constraints; transverse linearization; Automatic control; Reglerteknik; Automatic Control; reglerteknik;

    Sammanfattning : Nature and its variety of motion forms have inspired new robot designs with inherentunderactuated dynamics. The fundamental characteristic of these controlled mechanicalsystems, called underactuated, is to have the number of actuators less than the number ofdegrees of freedom. LÄS MER

  4. 4. Languages and Tools for Optimization of Large-Scale Systems

    Författare :Johan Åkesson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paper Machine Modeling; Plate Reactor; Languages for Physical Modeling; Compiler Construction; Dynamic Optimization; Modelica; Optimica; Manual Control; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Modeling and simulation are established techniques for solving design problems in a wide range of engineering disciplines today. Dedicated computer languages, such as Modelica, and efficient software tools are available. In this thesis, an extension of Modelica, Optimica, targeted at dynamic optimization of Modelica models is proposed. LÄS MER

  5. 5. High-Speed Vision and Force Feedback for Motion-Controlled Industrial Manipulators

    Författare :Tomas Olsson; Institutionen för reglerteknik; []
