Decentralization of Virtual Linkage in Formation Control of Multi-Agents via Consensus Strategies

Yi Liu, Junyao Gao, Xuanyang Shi, Chunyu Jiang
2018 Applied Sciences  
As compared to the original virtual linkage approach, the proposed approach uses decentralized architecture rather than hierarchical architecture, which does not require role assignments in each virtual  ...  In addition, each agent can completely decide its movement with only exchanging states with part of the team members, which makes this approach more suitable for situations when a large number of agents  ...  with only the exchange of state information with its local neighbors.  ...

Consensus over directed static networks with arbitrary finite communication delays

Jianquan Lu, Daniel W. C. Ho, Jürgen Kurths
2009 Physical Review E  
We study the consensus problem in directed static networks with arbitrary finite communication delays and consider both linear and nonlinear coupling.  ...  For the considered networked system, only locally delayed information is available for each node and also the information flow is directed.  ...  Moreover, the directed information flow is another important challenge for the consensus problem.  ...
