An Integrated Cyber-Physical Fault Management Approach

摘要

Fault-tolerance in distributed cyber-physical systems involves a close interplay between the physical system: the ’plant’ to be controlled and the distributed computing layer that controls it. In this paper, a systematic approach for designing resilient decentralized control applications is presented that considers both the cyber and physical faults and how they affect each other (if at all). It establishes a formal methodology for system design and then illustrates its use in an example application related to the power grid.
