Distributed Resilient Fixed-Time Control for Cooperative Output Regulation of MASs over Directed Graphs under DoS Attacks
New algorithm ensures robot teams complete missions on a fixed schedule even when 50% of communications are blocked.
A team of researchers has published a paper on arXiv titled 'Distributed Resilient Fixed-Time Control for Cooperative Output Regulation of MASs over Directed Graphs under DoS Attacks.' The work presents a new control algorithm designed for teams of robots or autonomous agents—known as Multi-Agent Systems (MASs)—that must coordinate to achieve a common goal, like forming a shape or reaching target positions. The core challenge addressed is maintaining this coordination even when an adversary launches Denial-of-Service (DoS) attacks, which block or disrupt the communication links between agents.
The proposed controller is 'fixed-time,' meaning it guarantees the system's regulated outputs (like position errors) will converge to zero within a mathematically proven time upper bound. Crucially, this time limit is independent of the system's initial state, offering predictable performance. Unlike many existing solutions, this new method does not require the communication network to be symmetric or satisfy a 'detail-balanced' condition, making it applicable to more realistic, flexible network topologies. The efficacy was validated through simulation, demonstrating that the agent team can successfully complete its cooperative output regulation task on schedule despite active communication attacks.
- Guarantees task completion within a fixed time limit, regardless of starting conditions or DoS attacks.
- Works on general directed communication graphs, removing need for symmetric or perfectly balanced networks.
- Enables reliable coordination for drone swarms, robot teams, or smart grids in contested environments.
Why It Matters
This research is critical for deploying autonomous swarms in real-world scenarios like disaster response or defense, where communication jamming is a real threat.
