  1. 1. Evaluation of electric actuation for fighter aircraft

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Dennis Moliner Pettersson; Anton Nygårds; [2023]
    Keywords : EMA; actuator; actuation; MEA; aircraft; PMSM; SHA;

    Abstract : The tendency of recent years towards electrification of aircraft components and subsys-tems has opened the door for a wider usability of electro-mechanical actuators (EMAs) inthat context. EMAs are already in use in aircraft industries but mainly in civil aviation forsecondary control systems and non-critical applications. READ MORE

  3. 2. Predicting power demand and optimizing energy management for fuel cell battery hybrid construction vehicles

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Abhishek Karthikeyan; [2023]
    Keywords : Fuel cell; Construction Vehicle; Energy management; Optimization; Model Predictive Control; Load prediction; Auto-correlation; Bränslecell; Byggfordon; Energihantering; Optimering; Modellförutsägande reglering; Belastningsprediktion; Autokorrelation;

    Abstract : The automotive industry has been actively seeking ways to reduce emissions and combat global warming. While pure battery electric vehicles have shown promise in achieving zero-tailpipe emissions, they face challenges in meeting the energy demands of large construction machines like excavators and wheel loaders, due to the heavy batteries required.

  4. 3. Commissioning of a FPGA/DSP unit for Centralized Control of a Variable Phase Pole Multiphase Machine

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jonas Hansson; [2022]
    Keywords : Harmonic Plane Decomposition; Multiphase Electrical Machine; Wound Independently-Controlled Stator Coils; System on a chip; Control Implementation; Hardware Design ; Motorstyrning; Asynkronmotor; Multifasmaskin; Programmering; Systemkrets; Hårdvarukonstruktion;

    Abstract : Multiphase Electrical Machines (MPEMs) with variable phase-pole configurations have recently gained interest as it offers advantages such as a larger operating range and improved fault tolerance compared to more traditional MPEMs. The current state-of-the-art modeling and control method, Vector Space Decomposition (VSD), has the drawback of introducing discontinuities in the model when transitioning from one phase-pole configuration to another.

  5. 4. Assessment of a Sustainable Water-based Lubricant for Electric Drivelines : Lubrication and Cooling performance of a Water-based Lubricant

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Ugo Jantel; [2022]
    Keywords : Water-based Lubricant; Cooling; Driveline;

    Abstract : In recent years, the impact of humans on the environment has been the subject of much debate. Car companies in particular are among the main actors in this environmental degradation with the polluting aspect of combustion cars. READ MORE

  6. 5. Dielectric Response of SiC-based Stress Grading Material Used in Electrical Machines

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Shilin Zhao; [2021]
    Keywords : Dielectric frequency response; End corona protection; Finite element method; High voltage rotating machines; Stator insulation; Dielektrisk frekvensrespons; Ändglimmskydd; Finita element metoden; Högspänningsmaskiner; Statorisolering;

    Abstract : High Voltage (HV) rotating machines are widely used in power generation and heavy industry companies. Silicon Carbide (SiC) material is used in the stress grading structure of HV electric machines because of its non-linear characteristic. READ MORE
