Abstract:
A method of estimating rotor speed of a generator 106 having a rotor 110 and a stator 112 is provided. The method may provide a source current to the stator 112, determine a relative rotor speed based on a sensor signal provided by a rotor speed sensor 130, determine a relative rotor position corresponding to the relative rotor speed, determine an absolute rotor position based on the sensor signal and phase currents, and calibrate the sensor signal based on an offset between the relative rotor position and the absolute rotor position.
