Critique of Several Failure Detection Approaches for Navigation Systems.

摘要

While the useful structural observations of 1 are laudable for applying Luenberger observers in detecting abrupt failures that may occur in deterministic time-invariant linear systems, it is reminded here that these new results are not appropriate to apply to the original navigation and avionics applications that motivated the precursor studies. The original motivating applications were described by stochastic linear systems and used Kalman filters to detect the occurrence of failures. Several barriers are reviewed here that plagued the predecessor investigations (but were previously overlooked) and unfortunately are still not circumvented by the novel approach of 1. Reprints.
