11. Solving a Dead-lock Problem of NFO-Sinus
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : This thesis presents, analyzes and suggests solutions to the dead-lock problem of the sensorless variable speed drive NFO Sinus. Friction, measurement, parameter estimation and quantization effects are believed possible origins of this problem and is hence studied. LÄS MER
12. Nonlinear Modeling of Locomotive Propulsion System and Control
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : In this report the motor side of a converter driven AC-locomotive is studied and modeled. The motor side consists of an asynchronous electrical engine, an indirect self controller, a voltage converter, a Pulse Width Modulator(PWM) and the train mechanics. The converter is supplied with voltage from a DC-link. LÄS MER
13. Reglering av siktesplattform med asynkronmotor
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : The task of this masters thesis is to investigate the properties of Natural Field Orientation, NFO, a new patented method for controlling the asynchronous motor. The intention is to see whether NFO would make it possible to, in the future, replace the expensive hydraulic motors that are being used in CelsiusTech Electronics' radar directors today with inexpensive hydraulic motors that are being used in CelsiusTech Electronics' radar directors today with inexpensive and robust asynchronous motors.
