...The GFRFs have their limitations: systems with non-fading memory, like non-local memory hysteresis as seen in friction, can not be described with GFRFs and GFRFs are difficult to interpret due to their multidimensional nature [17], [18]....

...The frequency domain based techniques for the analysis of nonlinear systems mentioned in literature can roughly be classified in three groups: Identification of the linear system In weakly non-linear systems the true linear system can be identified by minimizing the influence of the non-linear distortion using odd multisine excitation signals with minimized crest factor and with an amplitude kept as small as possible [1], [2], [3]....
