1. 16. 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. 17. Design, simulation and HIL testing of an electric propulsion system of an electric scooter with brushless DC motor using field-oriented control Digital Twin of an electric scooter

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Jatin Anand; [2021]
   Nyckelord :;

   Sammanfattning : A motor control algorithm to control a brushless DC motor has been implemented and tested in this master thesis. Model-based development approach has been applied to implement the entire system that includes the control algorithm (Field-Oriented Control) and the model of a brushless DC motor. LÄS MER

4. 18. Modelling and design of PMSM position drivesusing model following control

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

   Författare :JACOB RÖING; CARL JENSEN; [2021]
   Nyckelord :;

   Sammanfattning : Teenage Engineering is a Swedish electronics company that want to automate their quality control process. For this purpose, they want to develop a test jig that can perform tactile testing of their products. The test jig will utilize PMSM motors for position control of the end-effector. LÄS MER

5. 19. “All That Is Solid Melts Into Virtual Work”: A study of the implications of the Covid-19 pandemic on contemporary Employer Branding through the lens of Social Acceleration

   Kandidat-uppsats, Lunds universitet/Institutionen för strategisk kommunikation

   Författare :Henrik Ernstsson; Fredrika Hållén; [2021]
   Nyckelord :employer branding; employer brand; social acceleration; strategic communication; Spotify employer brand; work norms; social change; virtual work; remote work; digital labour landscape; resonance; Covid-19; arbetsgivarvarumärke; arbetsgivarvarumärkning; arbetsnormer; distansarbete; virtuellt arbete; digitala arbetslandskap; social förändring; Social Sciences;

   Sammanfattning : Impelled by the Covid-19 pandemic, the labour market is undergoing remarkable structural change towards increasingly digitized and remote forms of work. The purpose of this paper has been to study the social change in work norms instigated by the Covid-19 pandemic, with the aim of contributing to a more nuanced understanding of contemporary employer branding as a form of strategic communication in virtual and hybrid labour landscapes.

7. 20. Optimizing a servo drive using Field Oriented Control

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

   Författare :Lukas Land; [2021]
   Nyckelord :antenna; servo; foc; pmsm; vector engine; field oriented control; electrical motor; servo; fältorienterad kontroll; elmotor;

   Sammanfattning : An optimization of a servo system for a satellite antenna system wasperformed. A brushless DC motor with an angle encoder was used, whoseangular velocity had to be controlled with great precision. Specializedhardware was used to implement field oriented control to directlycontrol the torque and magnetic flux of the motor. LÄS MER
