  1. 1. Modelling and Control Methods with Applications to Mechanical Waves

    Författare :Hans Norlander; Bengt Carlsson; Torsten Söderström; Jonas Sjöberg; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automatic control; pole placement; linearization; vibration control; distributed parameter systems; wave propagation; Automatic Control; Reglerteknik;

    Sammanfattning : Models, modelling and control design play important parts in automatic control. The contributions in this thesis concern topics in all three of these concepts.The poles are of fundamental importance when analyzing the behaviour of a system, and pole placement is an intuitive and natural approach for control design.

  4. 3. Coordinated Control of HVDC Links in Transmission Systems

    Författare :Robert Eriksson; Lennart Söder; Kjetil Uhlen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coordinated control; dynamic security; exact-feedback linearization; feedforward control; HVDC poser modulation; Electric power engineering; Elkraftteknik;

    Sammanfattning : Dynamic security limits the power transfer capacity between regions and therefore has an economic impact. The power modulation control of high-voltage direct current (HVDC) links can improve the dynamic security of the power system. LÄS MER

  5. 4. CALLUM Linear Transmitter - Architecture and Circuit Analysis

    Författare :Roland Strandberg; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Telecommunication engineering; loop time delay; modulation negative feedback; spectral emissions; baseband model; CALLUM; Linear transmitter architecture; power amplifier linearization;

    Sammanfattning : This doctoral dissertation presents a study of linear radio transmitters based on the combined analog locked loop universal modulator (CALLUM) approach. Linear architectures such as CALLUM are very attractive for power-efficient operations, since they have no fundamental limitations prohibiting a 100% efficiency for all envelope levels, without sacrificing the potential of a linear transmission.

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

    Författare :Pedro La Hera; Anton Shiriaev; Ambarish Goswami; Umeå universitet; []
    Nyckelord :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
