“…To estimate the state and fault, References 24, 32 proposed distributed observer, the calculated amount of observer gains is limited by communication topology. In Reference 33, to achieve the desired formation, an active reconfigurable control protocol is proposed for MASs with multiple leaders. In Reference 34, based on the edge‐based adaptive law, the observer‐based protocol is designed for nonlinear MASs, which cannot extend to MASs with multiple leaders or directed communication topology.…”

This paper mainly studies the practical fault tolerant formation tracking for multi-agent systems under directed topology. The objective is to achieve the desired formation in the spatial positions and track the reference signal generated by one and multiple leaders. Considering that the real state information is unavailable, the distributed observer is proposed using the relative information of neighborhood agents, where the observer gain calculation is not constrained by the number of agents. With the adaptive updating mechanism, two effective distributed fault-tolerant formation tracking protocols are proposed and the feasible condition of time-varying formation is introduced. Furthermore, based on the proposed control protocol, the formation tracking errors and other signals converge to bounded region around the origin. Towards the end, three simulations are considered to illustrate the effectiveness of the proposed techniques.

“…Therefore, the fault‐tolerant control (FTC) strategy should be considered in the distributed secure formation control strategy to improve the performance of the faulty MASs. There are various works about fault‐tolerant control for consensus or formation problems 32–40 . However, faults are always addressed as a kind of disturbance, and are handled using passive fault‐tolerant methods, that is, fault values cannot be estimated exactly.…”

A distributed cyber-security and fault tolerance formation problem is considered in this paper. This is done though a multi-agent system in which all agents concentrate on a formation reference function and accomplish a desired time-varying formation even in the presence of malicious attacks and multiple faults. To achieve the resilient control task, a distributed control protocol using an event-triggered technique and active reconfigurable strategy is proposed in the face of adverse effects for the overall system. When denial of service is launched by adversaries, the attack parameters are bounded by analyzing the Lyapunov stability theorem and the property of the Laplacian matrix. To improve the capability of fault-tolerance, an observer-based fault estimator is used to calculate fault values. The simulation results validate that the presented scheme can perfectly address the distributed formation issue with faults over attack intervals.

“…For example, in [23], by applying a frequency-domain analytical method, the formation problem was studied for double-integrator FMASs. Liu et al in [24] designed an active reconfigurable control scheme to address the distributed formation tracking control problem for MASs with multiple leaders under actuator faults and constraints. In [25], Gong proposed an observer-based protocol to address the TVFC problem for FMASs with general linear dynamics, where the topology structure is selected as fixed and switched, respectively.…”

This brief investigates the Mittag–Leffler formation bounded control problem for second-order fractional multi-agent systems (FMASs), where the dynamical nodes of followers are modeled to satisfy quadratic (QUAD) condition. Firstly, under the undirected communication topology, for the considered second-order nonlinear FMASs, a distributed event-triggered control scheme (ETCS) is designed to realize the global Mittag–Leffler bounded formation control goal. Secondly, by introducing adaptive weights into triggering condition and control protocol, an adaptive event-triggered formation protocol is presented to achieve the global Mittag–Leffler bounded formation. Thirdly, a five-step algorithm is provided to describe protocol execution steps. Finally, two simulation examples are given to verify the effectiveness of the proposed schemes.
