  1. 1. Enhancing Servo System Performance : Robust Nonlinear Deadbeat Predictive Current Control for Permanent Magnet Synchronous Motors

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Xingyu Zhao; [2023]
    Nyckelord :keywords here: Deadbeat Predictive Current Control; Permanent Magnet Synchronous Motor; Flux Linkage Nonlinearity; Parameter Inaccuracies; Nonlinear Feedforward Compensation; Delayed Integral Action.; Deadbeat-prediktiv strömreglerin; Permanenta magnet-synkronmotorn; Ickelinjäriteter i flödeslänkningen; Felaktigheter i parametrar; Icke-linjär framåtmatningskompensation; Fördröjd integralåtgärd.;

    Sammanfattning : The Permanent Magnet Synchronous Motor (PMSM, also known as the servo motor) is a crucial component within robotic servo systems. To optimally respond to the torque demands sent from the high-level motion controller, the PMSM current controller must track the reference with speed and precision. LÄS MER

  3. 2. Simulating wave energy converter with twin generator torque converter in COMSOL

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Mashhur Billal; [2021]
    Nyckelord :Twin generator converter; dual generator; COMSOL; Savin; torque converter;

    Sammanfattning : Uppsala University has been spending a lot of time and resources in developing wave energy converters. In the test site of Lysekil, a full-scale point absorbing buoy with its associated components have been tested. From the test, various new information were discovered. LÄS MER

  4. 3. Hardware-In-the-Loop simulation of a small scale prototype of a Wave Energy Converter

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Nyckelord :Hydrodynamics; Hardware-In-the-Loop; WEC-Sim; Wave Energy Converter; NEMOH; Hydrodynamik; Hardware-In-the-Loop; WEC-Sim; vågenergikonverterare; NEMOH;

    Sammanfattning : Renewable energy sources are a hot topic, both when it comes to climate change and the constant increase in demand of electricity due to population growth and a more electrified society. One such energy source is wave energy - an energy source with great potential but still relatively new with the need for further development. LÄS MER

  5. 4. Konstruktionsutveckling av Garfieldlucka

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Willy Aron Gustafsson; [2020]
    Nyckelord :Maskinteknik; konstruktionsutveckling;

    Sammanfattning : In the converter hall at Rönnskärsverken in Skelleftehamn, there are three Pierce-Smith converters forthe manufacturing of copper. Associated with each converter is a converter hood whose purpose is todeal with the process gases that develop during the copper refining process. LÄS MER

  7. 5. Control of a Hydraulic Hybrid System for Wheel Loaders

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Christopher Reichenwallner; Daniel Wasborg; [2019]
    Nyckelord :EMS; Energy management strategy; Rule-based; Hydraulic hybrid; Wheel loader; Construction machinery; SLC; Short loading cycle; Torque converter; Energy recuperation; Energy efficiency; Backward simulation;

    Sammanfattning : In recent years many companies have investigated the use of hybrid technology due to the potential of increasing the driveline’s efficiency and thus reducing fuel consumption. Previous studies show that hydraulic hybrid technology can be favourable to use in construction machinery such as wheel loaders, which often operate in repetitive drive cycles and have high transient power demands.
