Abstract

Abstract:

The frequency-domain subspace system identification using non-parametric noise model is discussed in this paper, and a new flutter modal identification method based on subspace system is presented to identify the modal parameters from multichannel data.

Key words: flutter, , flight , testing, , modal , parameter, , frequency-domain, , subspace , system , identification
