“…Spawned by the rapid advances in networked systems and distributed cooperation, there has been a flurry of activity on the topic of multi-agent systems (MASs). During the past few years, MASs have found extensive application in both industrial and military domains, such as multi-robot systems [ 1 ], satellite formation control [ 2 ], sensor networks [ 3 ], smart grids [ 4 ], flight control systems [ 5 ], etc.…”

This article investigates the robust cooperative fault-tolerant control problem of multi-agent systems subject to mismatched uncertainties and actuator faults. During the design process of the intermediate variable estimator, there is no need to satisfy fault estimation matching conditions, and this overcomes a crucial constraint of traditional observers and estimators. The feedback term of the designed estimator contains the centralized estimation errors and the distributed estimation errors of the agent, and this further improves the design freedom of the proposed estimator. A novel fault-tolerant control protocol is designed based on the fault estimation information. In this work, the bounds of the fault and its derivatives are unknown, and the considered method is applicable to both directed and undirected multi-agent systems. Furthermore, the parameters of the estimator are determined through the resolution of a linear matrix inequality (LMI), which is decoupled by employing coordinate transformation and Schur decomposition. Lastly, a numerical simulation result is used to demonstrate the effectiveness of the proposed method.

“…Therefore, it is significant to improve system reliability and safety not only by designing fault tolerant control (FTC) to compensate the effect caused by faults automatically, but also by enhancing reliability of signal components. The approaches of the fault-tolerant design can be broadly divided into two categories: the passive one [1][2][3][4][5] and the active one [6][7][8][9][10][11]. Although the passive approach is usually exploited to handle partial actuator faults [12][13][14] and complete actuator faults [15][16][17], it has also a limited capability of handling unknown actuator faults due to its passive control laws being fixed.…”

“…Therefore, the fault tolerant flight control is particularly important for flight safety. Recently, the faulttolerant control has attracted the global attention of researchers [5][6][7][8][9][10]. To enhance the reliability and availability of the attitude control for tailless aircraft suffering from actuator faults, a multiple time-scale reconfigurable sliding mode control has been proposed in [11], nevertheless, only a linear model was considered.…”

This work investigates the anti-saturation attitude tracking control for the tailless aircraft with guaranteed output constraints, in presence of uncertain inertia parameters, bounded external disturbance, and actuator faults/failures. A predefined-time adaptive backstepping attitude control scheme has been proposed, the main features of this scheme lie in (a) designing a predefined-time filter to deal with the 'explosion of complexity' and singularity problem; (b) introducing a nonlinear state-dependent function to handle the asymmetric time-varying output constraints; (c) compensating for the impact of the actuator faults/failures and input saturation by a nonlinear function and bounded estimation simultaneously. Moreover, the proposed control scheme can ensure all signals in the closed-loop system converge to a residual set around the origin within a predefined time, and this time constant can be set freely by the designer, independently of initial conditions. Article Finally, numerical simulations have been conducted to verify the performance of the proposed predefined-time fault-tolerant control scheme.
