Sufficient Conditions on Bipartite Consensus of Weakly Connected Matrix-weighted Networks

no code implementations3 Jul 2023 Chongzhi Wang, Haibin Shao, Dewei Li

The positive/negative definite matrices are strong in the multi-agent protocol in dictating the agents' final states as opposed to the semidefinite matrices.

Vector-valued Privacy-Preserving Average Consensus

no code implementations22 Sep 2022 Lulu Pan, Haibin Shao, Yang Lu, Mehran Mesbahi, Dewei Li, Yugeng Xi

We show that the vector-valued PPAC problem can be solved via associated matrix-weighted networks with the higher-dimensional agent state.

Structural Adaptivity of Directed Networks

no code implementations28 Aug 2022 Lulu Pan, Haibin Shao, Mehran Mesbahi, Dewei Li, Yugeng Xi

Inspired by the observation that the link redundancy in a network may degrade its diffusion performance, a distributed data-driven neighbor selection framework is proposed to adaptively adjust the network structure for improving the diffusion performance of exogenous influence over the network.

A co-design method of online learning SMC law via an input-mappping strategy

no code implementations7 May 2022 Yaru Yu, Dewei Li, Dongya Zhao, Yugeng Xi

The major novelty of the proposed input-mapping sliding mode control strategy lies in that the sliding mode surface and the sliding mode controller are co-designed through online learning from historical input-output data to minimize an objective function.

A Cooperation-Aware Lane Change Method for Autonomous Vehicles

no code implementations26 Jan 2022 Zihao Sheng, Lin Liu, Shibei Xue, Dezong Zhao, Min Jiang, Dewei Li

Further, an evaluation is designed to make a decision on lane change, in which safety, efficiency and comfort are taken into consideration.

Distributed Neighbor Selection in Multi-agent Networks

no code implementations26 Jul 2021 Haibin Shao, Lulu Pan, Mehran Mesbahi, Yugeng Xi, Dewei Li

For distributed implementation, a quantitative connection between entries of Laplacian eigenvectors and the "relative rate of change" in the state between neighboring agents is further established; this connection facilitates a distributed algorithm for each agent to identify "favorable" neighbors to interact with.

Cluster Consensus on Matrix-weighted Switching Networks

no code implementations20 Jul 2021 Lulu Pan, Haibin Shao, Mehran Mesbahi, Dewei Li, Yugeng Xi

Second, if the underlying network switches amongst infinite number of networks, the matrix-weighted integral network is employed to provide sufficient conditions for cluster consensus and the quantitative characterization of the corresponding steady-state of the multi-agent system, using null space analysis of matrix-valued Laplacian related of integral network associated with the switching networks.

Dynamic Event-Triggered Consensus of Multi-agent Systems on Matrix-weighted Networks

no code implementations11 Jun 2021 Lulu Pan, Haibin Shao, Dewei Li, Lin Liu

This paper examines the event-triggered consensus of the multi-agent system on matrix-weighted networks, where the interdependencies among higher-dimensional states of neighboring agents are characterized by matrix-weighted edges in the network.

Characterizing Bipartite Consensus on Signed Matrix-Weighted Networks via Balancing Set

no code implementations28 Nov 2020 Chongzhi Wang, Lulu Pan, Haibin Shao, Dewei Li, Yugeng Xi

We show that necessary and/or sufficient conditions for bipartite consensus on matrix-weighted networks can be characterized by the uniqueness of the non-trivial balancing set, while the contribution of the associated non-trivial intersection of null spaces to the steady-state of the matrix-weighted network is examined.
