Abstract :
The accuracy of the modified interpolation method of nonlinear dynamical systems identification based on the Volterra model in the frequency domain is studied. The polyharmonic signals with reduced amplitudes are used as the test ones. The model is built as first, second and third order amplitude-frequency and phase-frequency characteristics. The comparison of obtained characteristics with previous works is given.
