This paper mainly concentrates on extracting dominant frequency estimates from sinusoidal signals corrupted with low frequency disturbances perturbation by means of a synthetic identifier in a real-time manner. It is assumed that the frequencies of such signals are unknown, and the magnitudes of the dominant signals are sufficiently large compared with those of disturbances. A state space based model for such sinusoidal signal is presented. The proposed frequency identifier consists of adoi:10.1109/acc.2011.5991338 fatcat:hlso2tvxubf7hescpweinvpawa
