More Information
Summary:Disclosed are an apparatus and method for adaptively compensating a position error of a resolver. The apparatus adaptively estimating a position error contained in position information of a rotor of a motor, which is digitalized by a resolver-digital converter, and subtracting the estimated position error from the measured position information of the rotor, thereby calculating compensated position information. A regression equation and a recursive least square method applied to the regression equation are used for the adaptive estimation of the position information.
