Fault-tolerant control of networked systems with re-distribution of control tasks in case of faults

摘要

The paper proposes a new method for fault-tolerant control of networked systems. The main idea is to re-distribute the common control task among the subsystems if the ability of a single subsystem to satisfy its specifications is limited by a fault. Two methods are proposed to find new set-points for the non-faulty subsystems such that the overall control goal is reached again. The main problem to be solved results from the fact that networked system do not have a coordinating unit and the subsystems have to agree about the re-distributed set-points by local information exchange. The ideas are illustrated by using a distillation process.
