A method for increasing the rate of parametric convergence in the problem of identification of the sinusoidal signal parameters

The problem of identification of the sinusoidal signal parameters is very popular in the modern theory and practice of the automatic control. However, the problem of quality of estimation related with the increase in the rate of parametric identification is studied weakly until now. At the same time, the requirements on the quality of processes at realization of the up-to-date systems represent one of the key criteria for selecting one or another approach. A new method for estimation of the sinusoidal signal parameters enabling an increase in the rate of parametric identification was proposed. Consideration was given to a signal representing a sum of two sinusoids which can be easily extended to a more general case.
