  1. 21. 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.

    Abstract : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. READ MORE

  5. 25. Extraction and optimization for modeling ofdesalination by capacitive deionization

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Max Rehman Linder; Zeshen Bao; [2023]
    Keywords : Desalination; Capacitive Deionization; ELC model; Adsorption; Simulation;

    Abstract : Water scarcity is set to become a big challenge in the 21st century and more efficient desalinationtechnologies will be needed in the future. In this project, one desalination method called capacitivedeionization (CDI) is explored and we used a model called the ELC model to simulate CDI withComsol. READ MORE
