Abstract

In recent work Pintelon et al. (2008) a single-output algorithm for continuous-time operational modal analysis in the presence of harmonic disturbances with time-varying frequency has been developed. This paper extends the results of Pintelon et al. (2008) to multi-output signals. The performance of the proposed maximum likelihood estimator is illustrated on real helicopter data.
