Mixed Delay and Threshold Voters in Critical Real-Time Systems

Abstract

This paper addresses the question of extending the usual approximation and sampling theory of continuous signals and systems to those encompassing discontinuities, such as found in modern complex control systems (mode switches for instance). We provide a topological framework derived from the Skorokhod distance to deal with those cases in a uniform manner. We show how this theoretical framework can be used for voting on hybrid signals in critical real-time systems.
