Abstract
A new algorithm for estimating the time-varying frequency of a noiseless sinusoidal signal is considered. It is assumed that the amplitude and frequency of the sinusoidal signal are unknown functions of time, but are solutions of linear stationary differential equations with known parameters. The problem is solved using gradient tuning algorithms based on a linear regression equation obtained by parameterizing the original nonlinear sinusoidal signal. The example presented in the article and the results of computer modeling illustrate the efficiency of the proposed algorithm, as well as explain the procedure for its synthesis.
