  1. 16. Real-Time Rotor Temperature Estimation Method for Interior Permanent Magnet Synchronous Machines : A method using a Lumped Parameter Thermal Network in combination with an estimation algorithm: implementation and comparison of a Dual Kalman Filter and a Dual Observer

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

    Author : Elvira Niemelä; [2022]
    Keywords : Permanent Magnet Synchronous Machine; Permanent Magnet Temperature Estimation; Lumped Parameter Thermal Network; Dual Kalman Filter; Dual Observer; Permanentmagnetiserad Synkronmaskin; Temperaturestimering för Permanentmagneter; Lumped Parameter Thermal Network; Dual Kalman Filter; Dual Observer;

    Abstract : Accurate knowledge of the temperature of a Permanent Magnet Synchronous Machine is of high importance, not only to ensure safe operation and improve control of the operating point, but also to avoid irreversible demagnetization of rare-earth permanent magnets. However, direct measurement using thermal sensors is not suitable for high volume and low-cost applications, due to costly sensor installation and maintenance, and therefore, the magnet temperature needs instead to be estimated.

  2. 17. Conductive interferences from multiple EC-motor installation : To measure and mitigate harmonics

    University essay from Uppsala universitet/Signaler och system

    Author : Victor Aitman; [2022]
    Keywords : harmonics; interharmonics; harmonic-mitigation; electromagnetic compability; EMC; övertoner; EC-motorer; störningar; övertonsreducering; elektromagnetiskt kompabilitet; EMC;

    Abstract : Products produced by a Swedish company are requested to be investigated regarding their harmonic and inter-harmonic currents injected into the public supply system to comply with the Swedish standard SS-EN IEC 61000-3-2, Electromagnetic compatibility (EMC).    On behalf of Systemair Sweden AB, this bachelor thesis aims firstly to investigate if their product, PAFEC 4225 WH (Air Curtain), complies with standard SS-EN IEC 61000-3-2, and if not, what measures should be taken; and secondly to develop a low-cost instrument for the measurement of harmonics and inter-harmonics according to standard IEC 61000-4-7 related to the requirements on equipment used in standard SS-EN IEC 61000-3-2.

  3. 18. Target Recognition and Following in Small Scale UAVs

    University essay from Uppsala universitet/Signaler och system

    Author : Ellen Lindgren; [2022]
    Keywords : autonomy; object following; object detection; Crazyflie 2.1; drone; quadcopter;

    Abstract : The industry of UAVs has experienced a boost in recent years, and developments on both the hardware and algorithmic side have enabled smaller and more accessible drones with increased functionality. This thesis investigates the possibilities of autonomous target recognition and tracking in small, low-cost drones that are commercially available today. READ MORE

  4. 19. Congestion Management of EV Charging in Distribution Networks

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Adam Rosandell; [2022]
    Keywords : Technology and Engineering;

    Abstract : The societal integration of electric vehicles (EVs) imposes several challenges on the electrical grid, where congestion and overcurrents through related components are of focus for this thesis. Active network management through control systems is one flexible solution to this problem, and in the project Active Network Management for All (ANM4L), a congestion management algorithm utilizing PI controllers has been developed.

  5. 20. Feasibility of the Implementation of Soft Landings in Sweden

    University essay from Lunds universitet/Byggproduktion

    Author : Nadja Pilav; Sebastian Eddin; [2022]
    Keywords : Soft Landings; delivery process; handover process; building performance; Technology and Engineering;

    Abstract : Title: Feasibility of the Implementation of Soft Landings in Sweden Authors: Sebastian Eddin & Nadja Pilav Supervisor: Stefan Olander Examiner: Rikard Sundling Close to 40 percent of global energy use is associated with the construction industry and building-related activities. Although several initiatives are underway both on national and international level from both the Swedish government and the European Union regarding energy efficiency, the construction industry is lagging behind, especially with regards to building performance.
