Time-domain approach for multi-exciter random environment test

TL;DR: In this paper, a time-domain method for multi-exciter random environment tests is presented, where the reference spectra are converted into timedomain response signals, and the finite long driving signals are derived by the state-space method with estimated state vectors.

Hybrid enhanced continuous tabu search and genetic algorithm for parameter estimation in colored noise environments

TL;DR: A new hybrid algorithm combining intelligent optimization techniques, i.e. enhanced continuous tabu search (ECTS) and elitism based genetic algorithm (GA) is proposed and is applied to the parameter estimation problem and results show that the parameters estimated using the proposed algorithm is unbiased in the presence of colored noise.

Signal denoising method for modal analysis of an offshore platform

TL;DR: It is found that the PEISVP-CE method is effective at eliminating noise and, therefore, appropriate for the modal analysis of offshore structures.
