EN This paper presents methods for parameter identification of mechanical resonance of multi-mass electrical drive system using nonlinear least squares method. The presented method was applied in the field of parameter identification of continuous-time liner dynamic system with delay. Results for two different excitation signals were presented: pseudo random binary signal and chirp wave. Spectral analysis was used to calculate frequency response data of electric drive with elastic connection. The discussed methods of identification are verified by both simulation and laboratory stand test.
