In cases where the input to a system is unknown or unmeasured, assumptions have to be made as to the nature of the excitation in order that modal parameters can be estimated from the response data alone. Commonly, an input signal is assumed to be 'white' random, as is any corruption of the response

Using the framework of the general structured (GS) observer, we present a straightforward procedurefor designing an unknown input observer (UIO) jor a linear O'stem subject to unknown inputs or uncertain disturbances. The set of all GS observers insensitive to unknown inputs is derived in this paper

This paper introduces a new structural identi"cation method for use in non-stationary conditions, which applies to structures and systems in normal serviceability conditions, under unknown excitation. The proposed method uses auto-and cross-time}frequency transforms of accelerometer signals recorded
