Experimental Application of Time-Domain Transmissibility Identification to Fault Detection and Localization in Acoustic Systems
TL;DR: In this article, a technique for fault detection and localization based on timedomain transmissibility identification is proposed, which takes the advantage of unknown external (ambient) excitation to identify a sensor-to-sensor model, which is independent of the excitation signal and the initial conditions of the underlying system.
Fault Detection, Identification and Accommodation Techniques for Unmanned Airborne Vehicles
TL;DR: A review of techniques that can be used to track the system health onboard a UAV, based on a year long literature review aimed at identifying approaches suitable for combating the low reliability and high attrition rates of today’s UAV.
