Observer-Based Self-Triggered Resilient Control for Multiagent Systems: A k -Connected Graph Construction Approach

This article investigates the problem of the fully distributed self-triggered secure synchronization control for multiagent systems (MASs) under communication link denial-of-service (CLDoS) attacks. First, an algorithm for constructing a k -connected graph is designed to reduce the impact of CLDoS attacks on MASs. Based on which, a fully distributed observer-based resilient control scheme is co-designed to reduce the dependence on the communication topology information. In addition, a self-triggered method is proposed to avoid the real-time monitoring of system information, further to reduce the resource consumption. Finally, the effectiveness and superiority of the construction algorithm and resilient control scheme are supported by comparison simulation examples.
