Abstract
In recent years, advanced fault detection technology is indispensable in space system development. Since human judgment of various diagnostic data is limited in complex systems such as spacecraft, it is necessary to introduce an autonomous fault detection system in order to prevent serious mission failures and system damages, and it can be expected to reduce human cost. One such method is Taguchi Method (Mahalanobis Taguchi system), which has been used to date for fault detection of artificial satellites and rockets. In this research, we focus on the Taguchi Method, and apply it to the fault diagnosis of adaptive space structures with advanced functions such as shape precision control and vibration control. In this report, we apply the Taguchi Method to the self-diagnosis problem that detects abnormality occurring in the smart structure from the vibration response data, and verify its usefulness experimentally.
