  1. 16. Analog mixed signal front-end for Torque signal processing : A theoretical noise analysis and signal-chain evaluation

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

    Författare :Jesper Jansson; Wilhelm Nordgren; [2023]
    Nyckelord :Torque sensor; noise analysis; signal processing; analog-to-digital conversion; Momentgivare; brusanalys; signalbehandling; analog-till-digital omvandling;

    Sammanfattning : High precision tightening of nuts and bolts together with traceability are important in many industrial assembly lines. To achieve this the nutrunner needs to accurately measure the torque which is applied to the nut, process the signal and provide the information to the controller that controls the tightening process.

  3. 17. Sensorless Field-Oriented Control and Position Estimation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Roberts Bitenieks; Lars Brander; [2023]
    Nyckelord :Sensorless rotor position estimation; High-frequency injection; Technology and Engineering;

    Sammanfattning : This master's thesis investigates the feasibility of implementing field-oriented control for a BLDC motor without relying on a position sensor from a standstill up to 400 rad/s. To achieve this objective, various approaches were used at standstill and high speeds. LÄS MER

  4. 18. Electric Leisure Boats: Enablers and Barriers : A case study of leisure boat manufacturers

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :FREDRIK IHRFELT; [2023]
    Nyckelord :Leisure boats; electric boats; electrification; technology management; innovation; industrial transformation; accelerators.; Fritidsbåtar; elbåtar; elektrificering; teknikledning; innovation; industriell transformation; påskyndare.;

    Sammanfattning : Combustion engines and fossil fuels have traditionally driven motor-powered leisure boats. Electrification is quickly transforming the transportation sector, but electric boats are rare. The primary drawback of the electric boat is the high production cost. LÄS MER

  5. 19. Analysis of Mutable Game Environments Built on a Tetrahedral Mesh : Tetras, a Potential Alternative to Voxels

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

    Författare :Noah Tell; [2023]
    Nyckelord :Voxels; Tetrahedron; Tetrahedral Mesh; Tetrahedralization; Tessellation; Mutable Environment; Editable Terrain; Deformable Environment; Boolean Operations; Real-Time; Computer Games; Computational Geometry; Voxlar; Tetrahedror; Tetrahedralisering; Tessellering; Formbar Terräng; Booliska Operationer; Realtid; Datorspel; Beräkningsgeometri;

    Sammanfattning : Historically 3D game environments have almost always been immutable. Mutable environments are a technical challenge that will affect performance. For games of the future to continue approaching realism, mutable environments are an essential step. LÄS MER

  7. 20. Small scale VTOL aircraft using only one lift-producing motor : A study of lift capacity for a Vertical Take-Off and Landing capable aircraft

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Daniel Milenkovic; [2023]
    Nyckelord :Aircraft; VTOL; EDF; Mechatronics; Ardupilot; Luftfarkost; VTOL; EDF; Mekatronik; Ardupilot;

    Sammanfattning : The usage of unmanned aerial vehicles in applications such as terrain mapping and surveillance is proliferating in the modern world. This project aims to investigate the feasibility, in terms of payload capacity and stability, of small scale winged aircraft that have the ability to lift and land vertically, while also being able to transition to normal forward flight using wings for primary lift.
