“…The best known method for determining the parameters of model (1) is the Prony method, which is often employed in virtual measurement systems [2][3][4]. This method consists of three main stages: determining the a j ; solving the characteristic equation z p + a 1 z p-1 + ... + a p = 0, the roots z i,i+1 = exp (a i ± j2πƒ i )∆t of which contain information on the eigenfrequencies and damping coeffi cients of the oscillations; and determining the complex amplitudes h j = U j exp (jϕ j ), j = 1, ..., p from the known roots …”
