FAULT RECOVERING TASKBLOCKS AND CONTROL SYNTHESIS FOR A CLASS OF CONDITION SYSTEMS

摘要

In this paper, we define fault recovery in terms of condition system languages, and show how to modify a component model to represent a fault that limits the functionality of a component. We also show under what conditions a control can be synthesized to work around such a fault. Finally, we consider the propagation of faulty behavior throughout the system and present an algorithm to evaluate whether some target specification is achievable by utilizing existing control synthesis techniques.
