“…The matrices C and A, as well as the modal parameters, might be retrieved from the obsessive-compulsive matrix O p+1 . Instead of using system identification, the fact is employed that damages cause changes in A and C and subsequently in H p+1,q through Equations ( 4) and (5). This fact will be directly tested in the statistical test.…”

“…Such techniques enable the evaluation of dynamic properties within customary operational conditions, obviating the requirement for human intervention. The evaluation of changes in damage-sensitive features derived from measurements in the system's current test state (possibly damaged or unhealthy) and its (undamaged or healthy) reference state can then be used to perform data-driven damage detection [4,5]. Because the features utilize ambient vibration data, statistical variability may have an impact on them.…”

“…Traditional dynamic parameters commonly employed for damage identification include natural frequency 21–23 and mode shape 24,25 . Natural frequency can be easily measured from several accessible points on the structure and is typically less susceptible to experimental noise.…”
