  1. 6. Field Oriented Current Control with Harmonic Injection in a Six-Phase Induction Machine

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

    Författare :Xinyue Shan; [2021]
    Nyckelord :Multi-phase machine; asymmetrical six-phase induction machine; harmonic plane decomposition; indirect rotor field oriented control; parameter estimation; Flerfasmaskin; asymmetrisk sexfasinduktionsmaskin; harmonisk plan sönderdelning; indirekt rotorfältorienterad styrning; parameteruppskattning;

    Sammanfattning : As a new type of machine, the multi-phase machine has the advantages ofhigher power rating, higher fault tolerance capability and more degrees offreedom to control compared with the traditional machine. Aiming at runninga multi-phase machine with different phase-pole configurations smoothly,a new method called harmonic plane decomposition is presented. LÄS MER

  3. 7. A Study on Fault-tolerance of Deep Neural Networks for Embedded Systems

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

    Författare :Elaheh Malekzadeh; [2021]
    Nyckelord :Embedded systems; Fault tolerance; Deep Learning; Single event upset; Edge AI.; Inbyggda system; Feltolerans; Djupinlärning; Edge AI.;

    Sammanfattning : Deep learning is replacing many traditional data processing methods in computer vision, speech recognition, natural language processing and many more diverse end applications. Until only a few years ago, using deep learning networks for inference required large amount of computational resources such as memory, processing power and energy. LÄS MER

  4. 8. Torque Ripple Analysis and Compensation of Servo Drives for Robot Application

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

    Författare :August Millqvist; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Permanent magnet synchronous motors or PMSMs are commonly used in multiple applications, both in industry and commercial use. These motors have many pros when compared to other electrical machines but do present the issue of torque ripple, especially cogging torque. LÄS MER

  5. 9. Active Control of High­-Speed Flexible Rotors on Controllable Tilting­-Pad Journal Bearings : Theory and Experiment

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

    Författare :Paul-Henrik Bull; [2021]
    Nyckelord :ATPJB; Fluid-Film Lubrication; Model based control; Vibration Control;

    Sammanfattning : A common choice of bearing for industrial applications such as turbomachinery and rotating compressors is the Tilting-Pad Journal Bearing (TPJB) due to its excellent stability properties. TPJB's are however limited by the reduction of damping in the fluid film at high velocities. LÄS MER

  7. 10. Fault current injection from power electronic interfaced devices

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

    Författare :Sandra Thengius; [2020]
    Nyckelord :;

    Sammanfattning : An increasing number of synchronous generators being replaced by renewable energy sources (RES) and HVDC links is expected in the future. HVDC links, some fast-growing renewable energy sources (RES) such as wind and solar photovoltaics, and system controllers such as STATCOM, have power- electronic interfaces to the grid. LÄS MER
