    Sammanfattning : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. LÄS MER

    Sammanfattning : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. LÄS MER

  5. 4. Design och framtagning avprototyp för reglering avhandtagsvärme på bensindriven motorsåg

    M1-uppsats, Karlstads universitet

    Författare :Axel Wedin; [2023]
    Nyckelord :;

    Sammanfattning : Husqvarna Group is a company specializing in forest and garden products. Among these products are chainsaws that incorporate functionality for handle heating. The current handle heating system is unregulated, and this report therefore addresses the development and construction of a prototype for controlling handle heating. LÄS MER

  7. 5. Utilizing Genetic Algorithm and Machine Learning to Optimize a Control System in Generators : Using a PID controller to damp terminal voltage oscillations

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Fredrik Strand; [2022]
    Nyckelord :AVR; AI; data-driven; GA; SVM; GPR; SVR; Ziegler-Nichols; Z-N;

    Sammanfattning : Hydropower is an important part of renewable power production in Sweden. The voltage stability of the already existing hydropower needs to be improved. One way to do this is by improving the control system that damp terminal voltage oscillations. LÄS MER
