  5. 19. Instrumentation and estimation for high temperature control

    Författare :Petter Hagqvist; Bengt Lennartson; Anna-Karin Christiansson; Mikael Sjödahl; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Automation; Emissivity; Emissivity Compensated Spectral Pyrometry; Laser Metal Wire Deposition; Metal Deposition; Pyrometry; Resistance Feedback Control; Thermometry; Varying Emissivity; Manufacturing and materials engineering; Produktions- och materialteknik; Physics; Fysik;

    Sammanfattning : Within a variety of industrially relevant high temperature production processes such as welding, heat treatment and metal deposition, the quality of the manufactured component is largely affected by how well parameters can be controlled during processing. These parameters might be, in the case of metal deposition, power input, material feed, or a parameter which is common for all of the aforementioned processes: material temperature. LÄS MER

  7. 20. Digital Compensation Techniques for Power Amplifiers in Radio Transmitters

    Författare :Jessica Chani Cahuana; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear system; linearization; power amplifier; iterative learning control; digital predistortion; Volterra series;

    Sammanfattning : Power amplifiers (PAs) are vital components in radio transmitters because they are responsible to amplify the low power communication signals to power levels suitable for transmission. Important requirements of PAs are high efficiency and linearity. Unfortunately, there is a tradeoff between efficiency and linearity. LÄS MER
