  1. 1. Evaluation of MPC and PI control on a Tribometer : Design and comparison of control methods for a Pin-on-Disc Tribometer

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Ehab Ziad Raheem; Tore Malmström; [2023]
    Nyckelord :Control Theory; MPC; PI; PI-Cascade; Tribometer; Pin-on-Disc; Reglersystem; MPC; PI; PI-Kaskadreglering; Tribometer; Stift-På-Skiva;

    Sammanfattning : This thesis compares Model Predictive Control (MPC) and Proportional-Integral (PI) control in a pin-on-disc tribometer. The tribometer consists of a geared Direct Current (DC) motor driving a flywheel and a voice coil actuating a pin onto the surface of the flywheel. LÄS MER

  2. 2. Evaluation of linear force actuators in a pin-on-disc test rig application

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :JAKUB JAN RUPNIEWSKI; [2020]
    Nyckelord :;

    Sammanfattning : This thesis presents an evaluation and comparison of two linear actuators that can be used as load application actuators in a pin-on-disc tribological test rig. The first actuator is a DC-motor with an external ball screw, and the second actuator is a voice coil. LÄS MER

  3. 3. Model based design of an expiratory valve and voice-coil actuator and evaluation of complete expiratory system performance with a PI controller

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :MIKKO KIESI; ROBERT AXELSSON SJÖBLOM; [2016]
    Nyckelord :model based design; mechanical ventilation; voice coil actuator; magnetic circuit; modellbaserad design; mekanisk ventilation; talspole aktuator; magnetisk krets; marginal;

    Sammanfattning : Mechanical ventilators are devices in critical care to assist breathing in case of expiratory dysfunction. The expiratory valve is a critical component to the ventilator as it controls the pressure in the patient’s lungs. LÄS MER

  4. 4. Voice Coil Controlled Inspiration and Expiration Valves

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Per Bergqvist; Linus Kemmler; [2012]
    Nyckelord :;

    Sammanfattning : This master thesis was performed at Maquet Critical Care located in Solna, Stockholm. Maquet Critical Care is a market leader in high performance medical ventilators. A ventilator is a medical device that helps patients to breathe. Two of the most vital components of a ventilator are the valves that are closest to the patient. LÄS MER
