Large Language Models to the Rescue: Deadlock Resolution in Multi-Robot Systems

no code implementations9 Apr 2024 Kunal Garg, Jacob Arkin, Songyuan Zhang, Nicholas Roy, Chuchu Fan

Multi-agent robotic systems are prone to deadlocks in an obstacle environment where the system can get stuck away from its desired location under a smooth low-level control policy.

Neural Graph Control Barrier Functions Guided Distributed Collision-avoidance Multi-agent Control

no code implementations21 Nov 2023 Songyuan Zhang, Kunal Garg, Chuchu Fan

We consider the problem of designing distributed collision-avoidance multi-agent control in large-scale environments with potentially moving obstacles, where a large number of agents are required to maintain safety using only local information and reach their goals.

Learning to Stabilize High-dimensional Unknown Systems Using Lyapunov-guided Exploration

no code implementations14 Jun 2023 Songyuan Zhang, Chuchu Fan

LYGE employs Lyapunov theory to iteratively guide the search for samples during exploration while simultaneously learning the local system dynamics, control policy, and Lyapunov functions.

Compositional Neural Certificates for Networked Dynamical Systems

1 code implementation25 Mar 2023 Songyuan Zhang, Yumeng Xiu, Guannan Qu, Chuchu Fan

Specifically, we treat a large networked dynamical system as an interconnection of smaller subsystems and develop methods that can find each subsystem a decentralized controller and an ISS Lyapunov function; the latter can be collectively composed to prove the global stability of the system.

Confidence-Aware Imitation Learning from Demonstrations with Varying Optimality
