  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. A simplified model for the design of floor structures with vibrating sources for architectural applications

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Rebecca Janson; [2019]
    Keywords : ;

    Abstract : When designing a building, sound is one of the problems to take into account. Vibrating machines, such as ventilation fans, water pumps and compressors, generate structure-borne sound. The structure-borne sound travels up the structure of the building and generates sound in adjacent rooms. READ MORE

  4. 3. Creating a Sustainable Water Access in Guinea-Bissau

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Lovisa Grönvik; Majken Domicelj; [2018]
    Keywords : Integrated product development; machine design; monotrailer; Integrerad produktutveckling; maskinkonstruktion; monotrailer;

    Abstract : In Guinea Bissau, one of the third most underdeveloped countries, there are many areas that are hard to reach by any other kind of vehicles than motorcycles – cars struggle with the poor road conditions. This means that many smaller communities, that are at a considerable distance from a larger road or city, become isolated and vulnerable. READ MORE

  5. 4. Inelastic LIDAR for Monitoring Aquatic Fauna

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Mikael Ljungholm; [2016]
    Keywords : LIDAR; Laser; hyperspectral; multispectral; inelastic; ecology; monitoring; plankton; aquatic; Scheimpflug; Technology and Engineering;

    Abstract : This thesis is oriented around designing the world first inelastic hyperspectral LiDAR(Light Detection and Ranging) system for aquatic use. The system was designed around the task of monitoring zooplankton and environmental indicators in water. Scheimpflug lidar was previously developed for monitoring flying insects, aerosols and gases.

  6. 5. Development of a method for studying cascading effects between critical infrastructures

    University essay from Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet; Lunds universitet/Riskhantering (CI)

    Author : Björn Arvidsson; [2015]
    Keywords : Cascading effects; critical infrastructure protection; incident investigation; conditions; counterfactual reasoning; empirical method; flooding; Technology and Engineering;

    Abstract : Most current methods for studying cascading effects rely on written sources to extract information. This thesis presents an empirical method for studying cascading effects, when little written information of the event is available. The method presented has been influenced by incident investigation methods. READ MORE
