ABSTRACT:
A resolver detected position compensation system for a resolver is provided that can enhance a position detection precision by performing a further compensation on a compensated position that was obtained from a static error compensation. The position detection circuit outputs a compensated detected position signal in which a static error has been compensated. The differential circuit differentiates the compensated detected position signal to obtain a rotational speed of the resolver. Based on a signal representing the rotational speed output from the differential circuit, the phase data memory device and the peak value memory device send the variation in phase and the amplitude peak value, respectively, of the dynamic error signal to the multiplication device. The multiplication device calculates an estimated dynamic error and the subtraction circuit removes the estimated dynamic error from the compensated detected position signal.
