A signal processing method based on resampling for quasi-constant-speed rotor signals

Accurate extraction of n× harmonic components is critical for rotor fault diagnosis but is challenged by speed fluctuations in quasi-constant-speed systems and the frequent unavailability of keyphasor signals. This paper proposes a novel resampling method based on the zero-crossing instants of the 1× rotational compone...
