  1. 1. Sensorless Control of Synchronous Machines in Python Using Signal Injection : An implementation of a High-Frequency Square-Wave Injection Algorithm on a Linear and Non-Linear Synchronous Machine Model in open-source Software Motulator

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

    Författare :Simon Lundberg; [2022]
    Nyckelord :High-frequency signal injection; Permanent Magnet Synchronous Motor; sensorless speed control; Synchronous Reluctance Machine; square-Wave injection; Fyrkantsvågsinjektering; högfrekvent signalinjektering; Permanentmagnetsmotor; sensorlös hastighetskontroll; synkron reluktansmotor;

    Sammanfattning : The importance of accurately controlling the speed and torque of Synchronous Machines (SMs) in industry, transportation, aerospace, to name a few, can not be overstated. The driving unit to control the machines are called Variable Speed Drives (VSDs) and they can be designed in many different ways. LÄS MER

  3. 2. Investigation of rotational velocity sensors

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Martin Törnquist; [2008]
    Nyckelord :sensor; sensors; GMR; Hall; Velocity; construction equipment; speed; Kalman; filtering; volvo; wheel loader; gear box; variable reluctance; magnetic field; rotation;

    Sammanfattning : To improve the speed measurement of construction equipment, different sensor technologies have been investigated. Many of these sensor technologies are very interesting but to keep the extent of the thesis only two was chosen for testing, magnetic absolute angle sensors using Hall and GMR technology, to investigate if those are a valid replacement for the current measurement system that is using a passive sensor.
