Abstract

This paper presents a bi-normalized frequency estimation algorithm which contains a two-dimensional state estimation equation and a one-dimensional frequency update rule coupled with it. The robustness of the algorithm is that the frequency estimation convergence is no longer subject to the actual value of the amplitude and frequency of the estimated signal. The asymptotic convergence of frequency estimation is demonstrated by Lyapunov stability theory, perturbation method, integral manifold and Mathieu equation, and the relationship between adaptive internal model algorithm and the proposed bi-normalization algorithm is analyzed. Simulation results verify the effectiveness of the proposed algorithm.
