Research on Hierarchical Consensus Fault-tolerant Control Strategy for Large-scale Facilities

Abstract

In the current major basic scientific fields, largescale experimental facilities play an important role. Due to the increasing number of control nodes, the strong interference conditions and network-induced communication constraints, it is easy to cause multiple faults that can reduce the control performance, and in the worst case it will lead to the instability of operation in the scientific experiment scene. To solve the problems of safe and stable operation, a hierarchical consensus fault-tolerant control strategy based on the networked multi-agent theory is proposed for large-scale complex control systems. Furthermore, a Large-scale control simulation platform for a large-scale laser facility is designed and implemented to verify the feasibility of the proposed method.
