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

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

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

    Abstract : 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. READ MORE

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

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

    Author : JAKUB JAN RUPNIEWSKI; [2020]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from KTH/Maskinkonstruktion (Inst.)

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

    Abstract : 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. READ MORE

  5. 4. Linearisation of micro loudspeakers using adaptive control

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska högskolan; Linköpings universitet/Institutionen för systemteknik

    Author : Ylva Björk; Ebba Wilhelmsson; [2014]
    Keywords : nonlinear control; loudspeaker; distortion; linearisation; Thiele-Small; Hammerstein-Wiener;

    Abstract : Loudspeakers were invented over 150 years ago, but the loudspeakers used todayare still based on the same ideas. Traditionally, good sound quality has been obtainedby using expensive materials in the loudspeakers and by allowing themto be big. READ MORE
