Abstract:
A method of compensating for rotor position error of a rotor of a permanent magnet synchronous generator (PMG) that provides electrical power to a direct current (DC) power generating system, the method including obtaining PMG phase voltages and resolver processed angular position output when the PMG is driven by a prime mover. Once obtained, a PMG fundamental phase voltage waveform is selected by eliminating higher order harmonics. A mechanical angle of the rotor is then converted into an electrical angle, then the electrical angle is aligned within the mechanical angle with a corresponding PMG fundamental phase voltage angle by adjusting offset to the electrical angle. After alignment, a plurality of resolver error offset values associated with the electrical angle are stored and additional values to the compensation table are added by interpolating data between two corresponding resolver error offset values of the plurality of resolver error offset values.

Claim (Index 1):
A method of compensating for rotor position error of a rotor of a permanent magnet synchronous generator (PMG) that provides electrical power to a direct current (DC) power generating system, the method comprising:\n obtaining PMG phase voltages and resolver processed angular position output signals by a resolver-to-digital (R/D) converter of the DC power generating system when the PMG is driven by a prime mover; selecting a PMG fundamental phase voltage waveform by eliminating higher order harmonics; converting a mechanical angle of a rotor into an electrical angle by an electrical angle and frequency derivation component of the DC power generating system; aligning the electrical angle within the mechanical angle with a corresponding PMG fundamental phase voltage angle by adjusting offset to the electrical angle; storing a plurality of resolver error offset values associated with the electrical angle into a computer readable storage medium of a digital signal processor (DSP) component; and adding additional values to the compensation table by interpolating data between two corresponding resolver error offset values of the plurality of resolver error offset values by a computer processor of the DSP component.
