Abstract
The paper is dedicated to problem of identification of unknown frequency of a biased sinusoidal signal y(t) = σ0 + σ sin(ωt +). A new proposed approach to estimation of frequency of biased sinusoidal signal is robust with regard to unaccounted disturbances, presenting in measurement of effective signal. Unlike known analogs, this approach allows to regulate time of estimation of unknown frequency ω. The proposed approach also allows online amplitude and bias estimation. Dimension of the proposed identification algorithm is less than known analogs have.
