“…As shown in Fig. 1, the MAS configuration considered in this paper consists of sensors, state observers, ETM, controllers, actuators, and the fault detection mechanism, in which the communication network between agents may be subject to FDIAs [14,15]. Besides, when a fault happens in an agent, the fault detection mechanism is to detect the fault promptly.…”

“…Compared with DoS attacks, FDIAs destroy the integrity and accuracy of the data by tampering with the transmitted information, and have stronger concealment [10]. However, research on the security of MAS under FDIA is still in the initial stage [11][12][13][14][15][16][17]. In [11,12], a control strategy with an adaptive attack compensator is proposed to ensure the uniformly ultimately boundedness of MAS under FDIA.…”

“…However, in practice, since the attacker needs to save energy to launch the next attack, it is impossible for the attacker to launch the attack continuously. To better reflect the reality, the model of FDIA that obeys Bernoulli distribution is considered in [13][14][15], and a distributed impulsive controller is proposed to deal with the control signals attacked by FDIA to ensure that the MAS can achieve mean-square bounded synchronization [14,15]. In these theoretical research, it is generally assumed that the state information of the system is measurable.…”

“…Taking into account the effects of external disturbance and stochastic FDIA, a state observer is designed to remove the assumption that the states of the agent are measurable as in [13][14][15]. In addition, it is worth mentioning that the state observation errors are first regarded as disturbance, and then attenuated by H ∞ norm bounds, together with the external disturbances.…”

This paper investigates the event-triggered observer-based security consensus and fault detection problem for nonlinear multi-agent systems (MASs) under external disturbances and stochastic false data injection attacks (FDIAs) over a directed communication network. The randomly occurring FDIAs are modeled by random variables that follow the Bernoulli distribution. An observer-based event-triggered control strategy using only local measurements and information from neighboring agents is developed, where the Zeno behavior of event-triggered mechanism (ETM) is excluded. Interestingly, the observer errors are first regarded as disturbance and then attenuated by H∞ norm bounds, together with the external disturbances. Meanwhile, it is worth highlighting here that the same information used by the state observers is also adopted to construct residuals with adaptive thresholds, whose aim is to detect faults occurring in any agents. In addition, the accuracy of the observer and the performance of the fault detection mechanism are improved by introducing the disturbance compensation mechanism. Finally, simulation results are provided to illustrate the effectiveness and advantages of the proposed strategy.

“…Therefore, it is essential to discuss the impacts of cyber-attacks in the investigation of various MASs [23][24][25][26]. In general, cyber-attacks can be categorized into deception attacks [27][28][29], replay attacks [30][31][32] and DoS jamming attacks [33][34][35]. Among them, DoS jamming attack is the most important and difficult to address.…”

This work focuses on the consensus problem of multi-agent systems (MASs) under event-triggered control (ETC) subject to denial-of-service (DoS) jamming attacks. To reduce the cost of communication networks, a novel event-triggering mechanism (ETM) is applied to the sleeping interval to determine whether the sampled signal should be transmitted or not. Unlike periodic DoS attacks model, the DoS attacks occurrence are irregular, where attack attributes such as attack frequency and attack duration are taken into account. Moreover, compared with the fixed topological graph, the communication topologies may change due to DoS jamming attacks in this work. In view of this, based on the piecewise Lyapunov functional, sufficient conditions are derived to guarantee that consensus problem of the MASs can be solved. Finally, the effectiveness and correctness of the theoretical results are verified by a numerical example.

This article studies a novel technique of the adaptive terminal sliding mode (TSM) control for the finite time stabilization of cyber-physical systems (CPSs).By using the proposed nonlinear sliding surface, the reaching mode is eliminated and the entire system robust procedure is ameliorated. The used adaptive laws are dealt with the cyber-attacks and external disturbances which their upper bounds are not needed to be recognized, where suggested approach is more pliable in the real performance. The presented new adaptive TSM control technique guarantees the system robustness versus cyber-attacks and external disturbances. Furthermore, the proposed control method obliterated the chattering behavior utilizing the hyperbolic tangent function and the continuous adaptive parameters in the control law. Numerical simulation results indicate the proposed adaptive TSM control technique's effectiveness and success compared to the results of state feedback control, conventional sliding mode control (SMC), traditional integral-type SMC, and adaptive integral-type SMC methods.
