“…Recently, the cooperative control of multi‐agent systems has received significant attention due to their wide use in, for example, sensor networks, distributed computation, distributed system optimization, congestion control, UAV control and so on . One of the fundamental problems in cooperative control is the consensus problem, requiring the design of a control strategy such that the states of all agents reach a common value.…”

This paper addresses the consensus problem of nonlinear multi‐agent systems with unknown external disturbance. First, a distributed observer is proposed to estimate the state and unknown disturbance of each agent simultaneously. Then, a novel event‐triggered control scheme based on the agent state estimation and disturbance estimation is proposed. Unlike the existing strategies, our event‐triggered conditions depend on agent state estimation and disturbance estimation, which are more effective and practical. Under this observer and control strategy, some sufficient conditions are derived to ensure the consensus of the multi‐agent system with unknown external disturbance. Moreover, the Zeno‐behavior of triggering time sequences is also excluded. Finally, a simulation example is given to verify the theoretical analysis.

“…Moreover, the sufficient conditions required to ensure consensus in mean square were derived by using the Lyapunov stability theory. Zhao and Dong (2017) added event triggering mechanism based on uniform fixed-time delay and studied the consensus of higher-order MASs with reduced-order observer-based protocol. Nevertheless, for homogeneous linear MASs, Li X et al (2019) proposed a novel reduced-order dynamic output-feedback protocol.…”

This paper considers a consensus control of a general linear multi-agent system with time-varying communication delays. Since each agent can only use the relative output information from its neighbors, a reduced-order observer-based control protocol is proposed to guarantee consensus on the directed communication network. The stability of the closed-loop system is analyzed for the cases with uniform delays and nonuniform time-varying delays, respectively. Moreover, the upper bounds of the communication delays are obtained respectively for the two cases. Finally, two numerical examples are provided to illustrate the proposed theoretical results.

“…Wang et al [26] investigate the reduced-order observer-based consensus problem of multi-agent systems with time delay and event trigger strategy. Zhao and Du [27] study the finite-time consensus problem of leader-follower higher-order multi-agent systems with mismatched disturbances by combining the non-singular terminal sliding-mode control and disturbance observer based control methods together. The introduction of state observer into the MASs is proven effective.…”

This paper is concerned with the distributed consensus problems for second-order multiaircraft systems in the presence of sensor data loss and time-varying communication topology. A novel model-based game strategy is proposed to handle the distributed problem regardless of the time-varying topology. An anti-disturbance sliding-mode controller is designed to realize the ability of disturbance rejection and state estimation. The extended state observer combines two methods together and finally produces an independent decision-making architecture for each individual such that better convergence is achievable. Theoretical analyses are given to guarantee both individual stability and distributed stability. The simulation and experimental results are presented to show the effectiveness of the proposed control scheme. INDEX TERMS Game theory, sliding mode control (SMC), multi-aircraft systems, time-varying topology.
