Fault diagnosis of adaptive beam using the Mahalanobis–Taguchi system

The application of adaptive structures (smart structures) in ultrahigh precision space structures such as X-ray astronomical satellites is being studied extensively. To ensure the reliability of such ultrahigh precision space structures, it is necessary to introduce an automated fault diagnosis system. In this study, the Taguchi method (Mahalanobis–Taguchi system) is applied to the self-diagnosis problem, wherein a damage in the smart structure is detected using the vibration response data of a smart beam. This article reports on the preliminary results of hardware experiments using a smart beam model in the laboratory.
