   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. 22. Utveckling av driftstöd för planering av fjärrkyla : En explorativ studie om utvecklingen av ett optimeringsbaserat driftplaneringsverktyg för fjärrkylanätet City i Linköping, Sverige

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Christian Haapanen; Louise Hedenskog; [2023]
   Nyckelord :District cooling; MILP; UC problem; Optimization; Operational plan; Smart energy systems; Fjärrkyla; MILP; UC problem; Optimering; Driftplanering; Smarta energisystem;

   Sammanfattning : The average global temperature is rising due to climate change. This leads to an increase in cooling demand along with higher usage of electricity to operate cooling processes. One way to decrease the electricity usage is to introduce absorption cooling which uses heat instead of electricity as its main source of power. LÄS MER

4. 23. Heating system performance and thermal mass evaluation of a former military building in mid-Sweden

   Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Javier Ruiz Pacheco; [2023]
   Nyckelord :Thermal mass; District Heating; IDA-ICE; Sweden; C02 emissions;

   Sammanfattning : The concern about global warming is gaining momentum. So, many initiatives, such as the Green European pact, which aims to reach to zero greenhouses emissions in 2050, are emerging to halt it. LÄS MER

5. 24. Neural Networks for Modeling of Electrical Parameters and Losses in Electric Vehicle

   Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap
