摘要: A simple method is proposed for estimation of amplitudes multiple sinusoids. The based on the existing adaptive identifier which offers globally convergent estimate sinusoidal frequencies. To deal with possible singularities amplitude estimation, observers are also amplitudes. Simulations illustrate results
