  1. 1. Provningsmetodik förkretskort, samt undersökningav termisktcyklade kretskort

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Robert Tüysüz; [2010]
    Nyckelord :;

    Sammanfattning : Lödfogar på kretskort utsätts för spänningar i samband med temperaturväxlingar. Dessa spänningar leder så småningom till utmattningsbrott. LÄS MER

  3. 2. IMPLEMENTATION OF ALGORITHMS ON FPGAS

    M1-uppsats, JTH, Data- och elektroteknik

    Författare :Mattias Karlsson; [2009]
    Nyckelord :C2H; FPGA; DSP; Algorithm; FOC; PMDC brushless motor; DO-254;

    Sammanfattning : This thesis describes how an algorithm is transferred from a digital signal processor to an embedded microprocessor in an FPGA using C to hardware program from Altera. Saab Avitronics develops the secondary high lift control system for the Boeing 787 aircraft. LÄS MER

  4. 3. Sensorless Control of a Permanent Magnet Synchronous Motor

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Fredrik Petersson; [2009]
    Nyckelord :Extended Kalman Filter; Non-linear Observer; Permanent Magnet Synchronous;

    Sammanfattning : A permanent magnet synchronous motor is traditionally controlled from measured values of the angular velocity and position of the rotor. However, there is a wish from SAAB Avitronics to investigate the possibility of estimating this angular velocity and position from the current measurements. LÄS MER

  5. 4. Adaptable rule checking tools for HDL

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Mikael Lord; [2009]
    Nyckelord :Lint; rule checking; safety-critical; VHDL;

    Sammanfattning : Today’s electronics in aviation (avionics) are more complex than ever before. With higher requirements on safety and reliability and with new SoC (System on Chip) technology, the validation and verification of designs meet new challenges. In commercial and military aircraft there are many safety-critical systems that need to be reliable. LÄS MER

  7. 5. ANALYSIS OF CASTING PROCESS FORCOMPLEX ELECTRONIC UNIT

    Master-uppsats, JTH, Maskinteknik

    Författare :Rebal Marcos; Endrias Teklu; [2009]
    Nyckelord :design for casting; casting process selection; simulation of rheocasting; simulation of plaster mold casting; casting cost estimation;

    Sammanfattning : Most aircraft component are currently being manufactured by machining, forging, welding and also assembling such parts. However, the possibilities of cutting cost from a single component has brought about a growing trend towards looking into casting as a possible option for manufacturing aircraft parts. LÄS MER
