到達可能性に基づく制御バリア関数を用いた先制的通信によるロバストなマルチエージェント追跡
Robust Multi-Agent Pursuit with Preemptive Communication via Reachability-Based Control Barrier Functions
断続的な通信下でもエージェント間の衝突回避を保証するため、到達可能集合と制御バリア関数を組み合わせ、不確実性と運動リスクに基づいて先制的に通信する手法を提案し、追跡・回避シナリオで通信量を77.5%削減した。

Safe multi-agent coordination typically assumes what real-world, deployed, resource-constrained robots cannot provide: continuous, perfect state sharing. Robust control strategies must be complemented with robust communication strategies to deliver resilient deployments. In this work, we propose a unified control/communication strategy that provides safe control to guarantee inter-agent safety under intermittent communication and demonstrate its effectiveness in a pursuit-evasion scenario. Each agent computes the reachable set of neighboring agents based on the last state information received, then solves for a safe control input based on control barrier functions to ensure agents avoid collision. We prove that inter-agent collision avoidance is guaranteed provided communication staleness remains bounded. As the reachable set inflates between state transmissions, each agent reasons about when to preemptively transmit its state information to neighboring agents based on novel metrics characterizing uncertainty risk and kinematic risk. We implement and simulate a variety of pursuit-evasion scenarios and show that preemptive communication reduces messages by 77.5% compared to periodic and event-triggered baselines with zero collisions.
