Solving a Dead-lock Problem of NFO Sinus
Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
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. A short introduction to ¯eld oriented control of the asynchronous AC motor and the NFO Control strategy is also included.
