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)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. Evaluation of linear force actuators in a pin-on-disc test rig application
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)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. 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.)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. Voice Coil Controlled Inspiration and Expiration Valves
Master-uppsats, KTH/Maskinkonstruktion (Inst.)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
