The article deals with the issue of identification of an unknown frequency of a shifted sinusoidal signal y(t) = σ 0 + σ sin(ωt + ϕ). A new approach taken to estimate the frequency of a shifted sinusoidal signal is suggested, which is a robust approach relative to undetermined disturbances present in the measurement of a useful signal. In contrast to known analogs, the given approach permits controlling the time of estimation of the unknown frequency ω. The dimension of the identification algorithm suggested is less than that of known analogs.
