Abstract
This paper presents an interpolation scheme for high-resolution rotor position estimation using data from a low-resolution encoder. The estimator is produced by incorporating a geometric polynomial equation into the rotor movement profile. The low and transient speed characteristics are examined and it is shown that the technique can produce effective resolution improvements by a factor of 16
