J. Vib. Acoust. 2007;129(6): doi: /
Figure Legend:
Damage identification results using noise-contaminated natural frequencies of the open-loop system, ad hoc closed-loop systems and optimal closed-loop systems, respectively. The noise level is v=2.0%. Black bars: actual stiffness reduction; Striped bars: prediction using noise-contaminated natural frequencies of the open-loop system; gray bars: prediction using noise-contaminated natural frequencies of the ad hoc closed-loop systems; checkered bars: prediction using noise-contaminated natural frequencies of the optimal closed-loop systems.
