nonlinear system identification; wavelet transform; coulomb friction; restoring force surface method
Abstract :
[en] 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.
