A method of compensating for rotor position error of a rotor (56) of a permanent magnet synchronous generator (PMG) (30) that provides electrical power to a direct current (DC) power generating system (20), the method including obtaining PMG phase voltages and resolver processed angular position output when the PMG (30) is driven by a prime mover (24). Once obtained, a PMG fundamental phase voltage waveform is selected by eliminating higher order harmonics. A mechanical angle of the rotor (56) 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.
