An Overview of Transient Fault Detection Techniques

This chapter overviews the theory and strategies of transient fault detection, considering both active and passive systems, and contrasting the more common frequent approaches with time-domain methodologies. The chapter contends that real complex systems may have mimics, where one characteristic can locally impersonate another. The chapter seeks to examine the “state of play” in these areas, providing a factual summary of what has been shown and demonstrated to date, along with a more speculative set of reflections about challenges and about which methods appear to the authors to have the greatest promise for deployment and commercialization.
