Abstract

The performances of sensorless flux observer and back-EMF methods of rotor position estimation in a brushless permanent magnet generator are compared. A simulation model is developed to investigate the accuracy of each method in the presence of electrical distortion and noise. Experimental results show that, over a speed range of 50 -500 rpm, the flux observer is significantly more accurate than the back-EMF method.
