  1. 16. 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

  3. 17. 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

  4. 18. Decentralized machine learning on massive heterogeneous datasets : A thesis about vertical federated learning

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Oskar Lundberg; [2021]
    Nyckelord :machine learning; federated learning; vertical federated learning; splitNN; decentralized machine learning; vFL; artificial intelligence;

    Sammanfattning : The need for a method to create a collaborative machine learning model which can utilize data from different clients, each with privacy constraints, has recently emerged. This is due to privacy restrictions, such as General Data Protection Regulation, together with the fact that machine learning models in general needs large size data to perform well. LÄS MER

  5. 19. Online parameter estimation in electric motors

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

    Författare :Abizar Sadikot; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The permanent magnet synchronous machine (PMSM) can be used for a wide range of applications. In this case, the motor that is examined is inspired of Husqvarna's handheld electrical tools where the motor is part of its electrical chainsaw. The idea is to investigate and simulate different algorithms for online parameter estimation for the PMSM. LÄS MER

  7. 20. Fault Detection in Permanent Magnet Synchronous Motors using Machine Learning

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Alexander Lennartsson; Martina Blomberg; [2021]
    Nyckelord :PMSM; Fault Detection; AI; artificial intelligence; Machine Learning; inter turn short circuit; inter turn short fault; turn-to-turn; permanent magnet synchronous motor; short circuit; fault; avionics; airplane; aircraft;

    Sammanfattning : In the aviation industry, safety and robustness are the number one priorities, which is why they use well-tested systems such as hydraulic actuators. However, drawbacks such as high weight and maintenance have pushed the industry toward newer, electrical, actuators that are more efficient and lighter. LÄS MER
