Formation Control for Moving Target Enclosing via Relative Localization

no code implementations28 Jul 2023 Xueming Liu, Kunda Liu, Tianjiang Hu, Qingrui Zhang

Based on the generation strategy of desired formation pattern and relative localization estimates, a cooperative formation tracking control scheme is proposed, which enables the formation geometric center to asymptotically converge to the moving target.

EASpace: Enhanced Action Space for Policy Transfer

1 code implementation7 Dec 2022 Zheng Zhang, Qingrui Zhang, Bo Zhu, Xiaohan Wang, Tianjiang Hu

In this paper, a novel algorithm named EASpace (Enhanced Action Space) is proposed, which formulates macro actions in an alternative form to accelerate the learning process using multiple available sub-optimal expert policies.

Lyapunov-Based Reinforcement Learning for Decentralized Multi-Agent Control

no code implementations20 Sep 2020 Qingrui Zhang, Hao Dong, Wei Pan

More importantly, the existing multi-agent reinforcement learning (MARL) algorithms cannot ensure the closed-loop stability of a multi-agent system from a control-theoretic perspective, so the learned control polices are highly possible to generate abnormal or dangerous behaviors in real applications.
