Abstract
Due to industrialization, there is a demand for rapid and highly accurate frequency estimator. The present paper tackles the identification problem of a damped sinusoidal signal in real time. To this end, an algebraic approach is employed. The authors derive an integral form of the frequency estimation algorithm by using the Laplace transform. In order to treat a noisy observation problem, the paper introduces a postfilter. The validity of the proposed algorithm is confirmed through numerical simulations in MATLAB/Simulink environment.
