Discussion on: 'Identification of Frequency of Biased Harmonic Signal'

摘要

The work of Aranovskiy, Bobtsov, Kremlev, Niko-laev, and Slita deals with the classical problem of designing an algorithm for the identification of the unknown frequency of a measured sinusoidal signal corrupted by bias and bounded non-periodic disturbances. They propose interesting contributions in this important and difficult field that has been visited by a large number of authors in the last decades. The result's main advantage with respect to similar schemes is to be small and simple, showing good performance in the simulations. The tuning procedure should be done carefully and could be greatly enhanced if based on prior approximative knowledge of the unknown frequency.
