Abstract
An absolute resolver digitizer for a numerical control system generating a digital number indicative of the absolute angular position of a resolver's rotor within a given revolution is disclosed herein. The resolver digitizer comprises a reference generator generating resolver excitation signals and a digital number indicative of the phase of the generated excitation signals and a resolver follower generating a digital number indicative of the sum of phase of the excitation signal generated by the reference generator and the angular position of the resolver's rotor. Subtraction of the digital number generated by the reference generator from the digital number generated by the resolver follower produces a digital number indicative of the resolver's absolute position within a given revolution. This subtraction may be performed by a separate circuit within the absolute resolver digitizer or may be performed by the computer associated with the numerical control system.
