Sensitivity and Computational Comparison of State-Space Methods for Structural Health Monitoring

摘要

Detection of the change in the vibration response of a structure as a means of damage detection has long been explored in the structural health monitoring field. Recently, damage detection metrics based on state-space attractor comparisons have been presented in the literature. This work compares various state-space attractor methods within an experimental context in an effort to determine the sensitivity of the methods to induced damage. The various methods are judged according to damage discrimination capability and computational effort.
