“…Formation control of MASs has been studied extensively over the past decades (see, refs. [8][9][10][11][12][13][14][15][16][17][18] and the references therein). Neural network-based, robust control, and event-triggered method are used respectively to address formation control problems for MASs with unknown nonlinear dynamics [8,9,17,18], with system uncertainties and external disturbances [13,14] and with switching topologies [15,16].…”

This paper explores finite-time formation control of multi-agent systems (MASs) with high-order nonaffine nonlinear dynamics and saturated input. Based on active disturbance rejection control theory, extended state observer is employed to identify unknown nonaffine nonlinear functions in MASs. The proposed control law consisting of backstepping control, tracking differentiator, and finite-time performance function is adopted for MASs to achieve the desired formation while reaching performance requirements. An auxiliary dynamic compensator is introduced to correct the control deviation caused by input saturation. Lyapunov stability theory is utilized to analyze the stability of the closed-loop system, which guarantees that the formation tracking error can asymptotically converge to an arbitrarily small neighborhood around zero in finite time. Finally, the simulation results show that compared to the adaptive, cooperative learning, and virtual structure methods, the proposed control algorithm has stronger tracking ability and faster setting time (1.8 s) under the influence of nonaffine nonlinear uncertainties. The integral square error for the formation control strategy in this paper is 0.16, which is much smaller than the abovementioned methods and is therefore provided to manifest the validity and feasibility of the proposed control strategy.

“…The fully distributed ETC schemes for linear and nonlinear MASs were investigated by Zhang et al [25] and Sun et al [26], respectively. In addition, for the network security issues, DoS attacks [27], deception attacks [28], and false data injection attacks [29] are usually considered for MASs, where the data injection attack (DIA) is extensively studied. Li et al [29] designed an ETC for discrete time-varying MASs with DIA.…”

This paper studies fully distributed data-driven problems for heterogeneous nonlinear discrete-time multiagent systems (MASs) with fixed and switching topologies preventing injection attacks. We first develop an enhanced compact form dynamic linearization model by applying the designed distributed bipartite combined measurement error function of the MASs,. we then an event-triggered control machination is developed and, a fully distributed event-triggered bipartite consensus framework is designed, where the dynamics information of MASs is no longer needed. Meanwhile, the restriction of topology is further relieved, which is fitting leader-less, leader-follower, and even containment control. Moreover, to prevent injection attacks, nervous network-based detection and compensation schemes are developed. Rigorous convergence proof is presented that the bipartite consensus error is ultimately boundedness by utilizing the Lyapunov stability theory. Finally, the correctness and effectiveness of the designed method are verified by simulation and hardware experiments.

This article investigates the event‐triggered consensus problem of general linear multiagent systems with denial‐of‐service (DoS) attacks. A distributed event‐triggered mechanism is presented to alleviate the limited communication resources, the designed mechanism is fully distributed owing to the introduction of some adaptive parameters. Moreover, since the DoS attacks have been considered in the event‐triggered rule design, a switching strategy for the adaptive parameters is adopted. A switching Lyapunov function is used to strictly demonstrate that secure consensus can be reached effectively under the proposed control mechanism. The quantitative relationship between the frequency of the DoS attacks and the consensus is also presented. Moreover, the Zeno behaviour can be excluded for the studied close‐looped systems. Finally, a numerical simulation example is given to demonstrate the validity of the designed control law.
