Abstract
An apparatus for compensating for a position information error of a resolver includes: a resolver-digital converter configured to generate a corresponding output angle by estimating resolver position information from a resolver output signal; and a position error compensation learner configured to determine a position error component in a corresponding electric angular velocity of the resolver output signal using the resolver output signal and the output angle and to convert the position error component to a position error component in an electric angular velocity 0. The resolver-digital converter compensates for an error by reflecting the position error component in the electric angular velocity 0 in the error between a position angle of the resolver output signal and the output angle.
