Dear editor,consensus turns out to be an important paradigm in coordination of multi-agent systems [1]. Previous studies largely concentrate on consensus problem over networks where the weights on edges are scalars, which cannot completely characterize the correlation of different dimensions corresponding to the state of an agent in the network.

This paper addresses the bipartite consensus over cooperation-competition networks affected by denial-of-service(DoS) *** that a network consists of multiple interactive agents, and the relationship between neighboring agents is cooperative or competitive. Meanwhile, information transmission among the agents is unavailable during the intervals of attacks. In order to save communication resources and exclude the Zeno behavior, an event-triggered scheme depending on the sampled-data information from neighboring agents is proposed, and efficient defense strategies in response to the attacks are put *** that the frequency and duration of DoS attacks meet certain requirements, then according to the signed graph theory,the La Salle’s invariance principle, and the convergence of monotone sequences, the results of bipartite consensus via the eventtriggered protocol are provided, which are mainly related to the communication topology of the network, the sampling period,and the threshold parameters in the event-triggered scheme. It is shown that the bipartite consensus is realized even though the DoS attacks take place frequently. Furthermore, this paper discusses the bipartite consensus in the presence of DoS attacks with a random unsuccessful rate. Finally, numerical simulations illustrate the theoretical results.

This paper is concerned with the problem of adaptive bipartite tracking problem for multi-agentsystems (MASs) over signed directed graphs with unknown nonlinear functions. Each followingagent is modelled by a higher-order nonlinear system in nonstrict-feedback form. The virtualand the actual control items of the considered system are the power functions with positive oddintegers rather than linear items. A distributed neural-based adaptive backstepping scheme isproposed, where the unknown nonlinear dynamics are approximated by Neural networks. Underthe proposed protocol, the bipartite output tracking errors converge to a small neighbourhoodof the origin and all the signals of the closed-loop system remain semiglobally uniformly ultimatelybounded. Since the considered high-order non-strict feedback nonlinear MASs in ourpaper include some existing nonlinear MASs as the special case, our result can be extended tocontrol more general nonlinear MASs. Finally, the simulation results illustrate the validity of theproposed schemes by a numerical example and a practical example about a group of forceddamped pendulums.

bipartite consensus for Multi-Agent Systems with Differential Privacy Constraint

第40届中国控制会议

作者： Guodong Ma Jie Ren Min Zhao Guoping Lu School of Electrical Engineering Nantong University Department of Science Nantong University Xinglin College School of Science Nantong University

This paper investigates the bipartite leader-following consensus problem for multi-agent systems with nonlinear dynamics and multi-layer signed digraph topologies. According to the structural balance theory, some sufficient conditions are explored for reaching the bipartite leader-following consensus of the multi-layer signed networks by using the pinning control strategy, which are related to the dynamics of the network nodes and the topology of the multi-layer signed network. These conditions are also suitable for traditional single layer signed networks. The numerical example shows the correctness and effectiveness of the proposed method.
