  1. 1. A personalized quasi-passive ankleexoskeleton using human-in-the loop optimization approaches

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ho Ming Kong; [2023]
    Keywords : ;

    Abstract : Passive ankle exoskeletons have been proven to successfully decrease muscle demand for walking. The movement of the user’s ankle drives a mechanical clutch and spring, which eventually stores and returns mechanical energy to the user. READ MORE

  3. 2. Sensorless Hybrid Field-Oriented Control Two-Phase Stepper Motor Driver

    University essay from Linköpings universitet/Reglerteknik

    Author : Emil Lydell; [2023]
    Keywords : Stepper motor; Field-Oriented Control; FOC; Driver; Two-Phase; 2-Phase;

    Abstract : Hybrid stepper motors are small electrical motors with high torque production, compared with other electrical motors of the same size. Hybrid stepper motors are reliable in open-loop systems, in Sinusoidal mode, but with a drawback of high power consumption. READ MORE

  4. 3. Sustainable Production Patterns for Hydropower Units

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Hannington Kayanja; [2023]
    Keywords : Automatic control; Hydropower modelling; PD-controller; Sustainable power production; Water level control.;

    Abstract : Globally, a significant portion of energy comes from hydropower. However, harnessing hydro energy interrupts the natural state of river flows, thus affecting the ecological processes of the surrounding communities. READ MORE

  5. 4. Sensorless Control of Synchronous Reluctance Machines and Permanent Magnet Synchronous Machines for Pump Applications

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