Abstract. The problem of identifying time-varying frequency of sinusoidal signal is considered. Using the iterative parameterization procedure, dynamic regressor extension and mixing technique, and Luenberger observer, estimations of non-stationary parameters are designed. Presented results of numerical simulation, the proposed algorithm efficiency is demonstrated.
Keywords: parameter identification, non-stationary frequency, Luenberger observer, DREM
