TL;DR: In this article, two algorithms are developed for the estimation of the parameter drift rate, and the performance of the developed algorithms is also evaluated, based on the performance evaluation of the tested algorithms.
Abstract: System faults may be detected and predicted via estimation of trajectories of the system dynamic parameters in the parameter space. During normal operation, the parameters exhibit random motion around their nominal values. A drift of one (or more) parameters may indicate a fault. Two algorithms are developed here for the estimation of the parameter drift rate. The performance of the developed algorithms is also evaluated.
