General method for tracking the evolution of hidden damage or other unwanted changes in machinery components and predicting remaining useful life
TL;DR: In this paper, a method and apparatus for determining a slowly evolving damage state in a system having a time scale separation between a fast subsystem and a slow subsystem is presented, the method includes acquiring measurement data of the fast subsystem of said system, determining a tracking function for the system, and evaluating the tracking function using the acquired measurement data to determine a measure of the slow damage subsystem the system.
