A position tracking manage approach primarily based on an eventtriggered mechanism for UAVs with many state time delays and external disturbances is designed in [36]. A communication network offers comfort and efficiency within the facts exchange among UAVs. Nevertheless, it brings quite a few challenges for the control of multiUAV systems, including the network safety trouble. Amongst the different elements impacting network security, cyber attacks [37,38] are able to exhaust network resources and may trigger failures of crucial tasks. The network attack involves denial of service (DoS) attack [39,40], replay attack [41], deception attack [424] and so on. The DoS attack might prevent the timely details exchange [45]. With respect to the replay attack, the attackers maliciously transmit the received data repeatedly within a particular period of time, which may well lead to repeated unnecessary operations [46]. The deception attack will result in the Biotin-azide Autophagy incompleteness of data by replacing or stealing the data, which could result in the instability, as well as executions of guidelines from the attackers [47]. In comparison to the aforementioned two forms of cyber-attacks, the deception attack is difficult to detect and avert [48]. Thus, much work has been devoted to alleviating the adverse impacts from deception attack, and wonderful progress has been made in N-Nitrosomorpholine custom synthesis recent years [492]. As far as we know, couple of outcomes are accessible on consensus or formation control troubles for multi-UAV systems with deception attacks. Wang et al. investigate the formation manage trouble of a number of robots beneath deception attacks. Nonetheless, the ETM will not be utilized to alleviate the communication burden [53]. A novel formation control law based on ETM is proposed in [54]; nonetheless, the deception attack will not be thought of in the proposed method. In addition, only time-invariant formations are realized in [54]. Thus, the time-varying formation tracking (TVFT) control dilemma primarily based on ETM for multi-UAV systems subjected to deception attacks needs much more investigation. Inspired by the observations above, we propose an integrated event-triggered formation tracking control scheme for multi-UAV systems with deception attacks. The key contributions of this study might be summarized as follows. (1) An ETM is proposed for multi-UAV systems with time delay. Compared with all the event-triggered mechanisms in Ref. [12], the data of each the leader and also the formation is utilized to style the triggering situation, which reduces the quantity of redundant data and alleviates the communication burden. Compared with all the event-triggered mechanism in Ref. [54], time delay is taken into consideration, which tends to make the created ETM a lot more affordable and realistic. The presence of time delay brings a sizable challenge to the theoretical evaluation and acquiring a feasible remedy by LMI considering the fact that the Lyapunov function is additional complex, when compared with the one in [54]. (two) A novel time-varying formation tracking handle method is developed for multiUAV systems beneath deception attacks. As far as we know, few outcomes simultaneously take the TVFT manage and deception attack issues into consideration. Diverse from the existing benefits on multi-UAV systems devoid of cyber attacks [2,19], th.
