The secure consensualization for leaderless nonlinear multiagent systems with communication link attacks is realized in a fully distributed manner in a certain sense that the gain matrix design do not depend on the communication topology.A new virtual reference state estimator is proposed for each agent to estimate the common tracking state, which can adaptively adjust coupling strengths to counteract the influence of communication link attacks. Then, by the Lipschitz condition and the special structure property of the time-varying nonsingular transformation matrix, the influence of the Lipschitz nonlinearity on secure consensus is linearized, and a design approach of the secure consensus control gain is given on the foundation of the linear matrix inequality. Finally, a numerical example is provided to demonstrate the effectiveness of theoretical results.

Fully distributed consensus control is one of the important topics in the above fields, which needs that all agents reach agreement on some interesting variables by constructing the consensus protocol in a fully distributed manner. Some fully distributed consensus protocols and important conclusions were shown in References 11-15, where the influence of the communication link attack or fault was not considered. With the rapid advancement of artificial intelligence and information technology, the communication link attack is an important threat for MASs. Attacks on the communication link can block the communication channels among agents, and can cause the data information transmitted in the communication topology to be unavailable or invalid, which may seriously damage the consensus properties of the whole system. This motivates researchers to study secure consensus control (SCC) for MASs with communication link attacks.

“…D URING the past years, numerous researchers have concentrated their efforts on multi-agent systems (MAS), which are made up of multiple agents that collaborate with their neighbors. The distributed cooperative control of MAS has widespread applications in wireless sensor networks, intelligent transportation, robot systems [1]- [6], and so on. As a basis and key issue for cooperative behavior of MAS, its consensus problem has raised a hotspot in the system control field.…”

Observer-Based Distributed Event-Triggered Secure Consensus of Multi-Agent System With DoS Attack

et al. 2023

This paper addresses the distributed secure consensus problem for linear multi-agent systems (MAS) with unmeasurable states and Denial-of-Service (DoS) attacks. The observer is designed to be used in estimating unmeasurable states of agents. Then, an observer-based distributed event-triggered control protocol is proposed to save network resources. By using the piecewise Lyapunov function approach, several sufficient conditions for ensuring secure consensus are obtained. Further, a rigorous theoretical analysis shows that the given event-triggering scheme exhibits no Zeno behavior. Finally, the effectiveness of the proposed method is verified by numerical simulation.

“…Interconnected networks consist of multiple intelligent agents, where the various coordinated behaviors of interconnected networks emerge by different information interaction rules among agents. Those coordinated behaviors contain the synchronization behavior, [1][2][3] the flocking behavior, 4,5 the cooperative fusion behavior, [6][7][8] and the formation behavior [9][10][11] and so forth where their emergency mechanisms were investigated from the different perspectives. It should be pointed out that the research of the formation behavior is inspired by the investigation of the emergency mechanism of the flocking and consensus behaviors, where the flocking and consensus behaviors emphasize the theoretical discussions, while the formation behavior owns potential applications with practical backgrounds, such as the coordinated operation of multiple androids and the cooperative detective of multiple unmanned underwater vehicles.…”

The minimum‐energy formation tracking design and analysis problems for interconnected networks with distributed tracking protocols are addressed, where the effects of the total energy restriction and the interaction silence on the formation tracking are discussed, respectively. The key characteristic of this article is that the value of the energy restriction is required to be minimum, while the guaranteed‐cost tracking strategy and the energy‐constraint tracking strategy cannot ensure the minimum property of the total energy restriction. For interconnected networks without the interaction silence, sufficient conditions for minimum‐energy formation tracking are presented, whose effectiveness can be checked by the optimization procedure associated with the generalized eigenvalue method. Then, for interconnected networks with the interaction silence, by constructing the specific constraint associated with the maximum silent rate and two inhibition parameters, sufficient conditions for minimum‐energy formation tracking are proposed. Finally, numerical examples are shown to illustrate the efficacy of main results.
