Abstract

This paper describes a methodology for implementing bidirectional frequencyโ€selective filters in cases where the data sequence is short and nonโ€stationary. A simple method is proposed for dealing with the startโ€up problem. The method has a firm theoretical basis and it is computationally efficient. Copyright ยฉ 2001 John Wiley & Sons, Ltd.

Non-stationary time-frequency analysis is used for identification and classification of aeroelastic and aeroservoelastic dynamics. Time-frequency multiscale wavelet processing generates discrete energy density distributions. The distributions are processed using the singular-value decomposition (SVD
