Abstract: The identification of a nonlinear system is performed using
experimental data and two different techniques, i.e. a method based on the
Wavelet transform and the Restoring Force Surface method. Both techniques
exploit the system free response and result in the estimation of linear and
nonlinear physical parameters.
Keywords: nonlinear system identification, wavelet transform, coulomb friction, restoring force surface method
