  1. 1. Sensorless Control of Synchronous Reluctance Machines and Permanent Magnet Synchronous Machines for Pump Applications

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

    Author : Erik Lindberg; [2023]
    Keywords : Variable speed drives; Sensorless control; Luenberger observer; Synchronous reluctance machine; Permanent magnet synchronous machines; Vector control; Model reference adaptive system; Variabel hastighetsreglering; Sensorlös reglering; Luenberger observatör; Synkron reluktansmaskin; Permanentmagnetmaskin; Vektorreglering; Adaptiv modelreferensreglering;

    Abstract : Energy efficiency in electric machines is both environmentally and economically important. Water pumps with an integrated Variable Frequency Drive (VFD) and a Permanent Magnet Synchronous Machine (PMSM) have challenged the status quo of the Induction Machine (IM) for water pumps.

  3. 2. 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

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

    Author : Simon Lundberg; [2022]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 3. Evaluation of a Switched Reluctance Machine in an Automotive Oil Pump Application

    Keywords : SRM; Switched Reluctance Machine; Instantaneous Torque Control; Average Torque Control; Flux Based Position Estimation; Sensorless; 4 2 asymmetric SRM; Technology and Engineering;

    Abstract : A Switched Reluctance Machine (SRM) is evaluated in terms of torque quality and speed ripple for a particular pump application. The aim is to give BorgWarner insight into the control methodology and possible applications for a Switched Reluctance Machine. READ MORE

  5. 4. Investigation of Sensorless Control of Permanent Magnet Synchronous Motor Using High Frequency Injection

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Lucas Bergstrand; [2020]
    Keywords : ;

    Abstract : This thesis implements and analyses a sensorless control method for permanent magnet synchronous motors. The purpose is to investigate if the results presented in a study performed by Millinger et al. can be replicated on an industrial grade embedded control system. READ MORE

  6. 5. Design and implementation of sensor-based and sensorless control of a PMSM test system

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

    Author : Oskar Giesecke; [2019]
    Keywords : ;

    Abstract : Transportation of liquids and gasses in industries in forms of pumping and fanning, constitutes asignificant part of the world-wide electric energy consumption. In order to meet global environmentalgoals of greenhouse gas emissions and sustainable material usage, the development of efficiency andtechnical lifetime of industrial pump and fan technology, are key.
