Fault Detection and Identification of Smart Structures via Mahalanobis-Taguchi System

Abstract

Taguchi Method (Mahalanobis-Taguchi system) is widely used for fault detection of complex systems and industrial products including applications in Space Engineering. In this research, we focus on the Mahalanobis Taguchi (MT) system, and apply it to the fault diagnosis of adaptive space structures with advanced functions such as high precision shape control and vibration control. In this paper, we apply the Taguchi Method to the self-diagnosis problem that detects the failure in the smart structure using the random vibration response data, and verify its usefulness experimentally.
