[en] The objective of this technical note is to explore the applicability of a newly introduced nonlinear
system identification technique to spacecraft structures. To this end, numerical experiments are conducted using a finite element model of the SmallSat spacecraft. A detailed introduction to the method, referred to as the frequency-domain nonlinear subspace identification (FNSI) method, is provided and its major assets are commented. Random-type and sine-sweep excitations are considered and identification results are extensively discussed.
