“…Compared with the Ref. 14 , the trajectory tracking control method proposed in this paper utilizes the ACK technology to nest a new handover scheme on the periphery of the switching-like ETS for handling the DoS attacks. Moreover, together with the switching-like ETS, the observers and the controller with switch gains are presented on the basis of the properties of DoS attacks.…”

“…To name a few, the Ref. 14 , a trajectory control scheme based on hybrid ETS was proposed for UAH/UGV systems subject to time-delay, external disturbance, and deception attacks. It is worth noting that since DoS attacks prevent data packets from being transmitted via the network, this kind of cyber-attack would heavily ruin the tracking control performance for the UAH/UGV systems, which remains important and challenging.…”

“…Thus, the Ref. 14 proposed a hybrid ETS to decrease the number of transmitted data and achieve ideal control performance, which could combine the advantages of conventional ETS and memory ETS. Yet, as for network-based control systems, it is required that not only less data transmissions but also cyber-attacks need to be considered.…”

“…Yet, as for network-based control systems, it is required that not only less data transmissions but also cyber-attacks need to be considered. Then the hybrid ETS in 14 cannot simultaneously tackle these unfavorable factors in some complicated cases, which motivates this paper to propose a design of switching-like ETS.…”

In this paper, by considering the existence of unavailable state, external disturbance, and denial of service (DoS) attacks, an anti-disturbance trajectory tracking controller is proposed for the air-ground system composed of unmanned autonomous helicopter (UAH) and unmanned ground vehicle (UGV). Initially, by combining the advantages of conventional event-triggered scheme (ETS) and memory ETS, a switching-like event-triggered mechanism is put forward, which can cause less data transmissions without reducing control performance, and effectively restrain the DoS attacks. Secondly, by dividing the DoS attacks into active intervals and sleep ones, the concept of acknowledgement character technology (ACK) is presented to determine the suitable type of time intervals. Thirdly, the switching-like dynamic ETS is introduced for the sleep intervals of DoS attacks while the ETS with fixed triggered-threshold is exploited for the active intervals. Fourthly, based on the occurrence of the DoS attacks, a switching-like observer and a normal one are respectively proposed to estimate the UGV state, the UAH state, the reference input of the UGV, and the disturbance of the UAH, which are utilized to design the anti-disturbance tracking controller. Fifthly, an augmented closed-loop system consisting of observation errors and tracking error is established and its stability is analyzed by using Lyapunov stability theory. Then, a sufficient condition on co-designing the parameters of switching-like ETS, observers, and tracking controller is presented in terms of linear matrix inequalities (LMI). Finally, the validity and superiority of the proposed control scheme are verified by resorting to simulations and comparisons.

“…However, since the UAH and the UGV need communication network to transmit the data of position and velocity, these above studies considered the ideal case and ignored some unfavorable factors such as resource limitations, cyber‐attacks, and so on. To name a few, Reference 14, a trajectory control scheme based on hybrid ETS was proposed for UAH/UGV systems subject to time‐delay, external disturbance, and deception attacks. It is worth noting that since DoS attacks prevent data packets from being transmitted via the network, this kind of cyber‐attack would heavily ruin the tracking control performance for the UAH/UGV systems, which remains important and challenging for the studies.…”

In this article, by considering the existence of unavailable state, external disturbance, and denial of service (DoS) attacks, an anti‐disturbance trajectory tracking controller is proposed for the air‐ground system composed of unmanned autonomous helicopter (UAH) and unmanned ground vehicle (UGV). Initially, by combining the advantages of conventional event‐triggered scheme (ETS) and memory ETS, a switching‐like event‐triggered mechanism is put forward, which can induce less data transmissions without reducing control performance, and effectively restrain the DoS attacks. Second, by dividing the DoS attacks into active intervals and sleep ones, the concept of acknowledgement character technology (ACK) is presented to define the suitable types of time intervals. Third, a switching‐like dynamic ETS is introduced for the sleep intervals of DoS attacks while the ETS with fixed triggered‐threshold is exploited for the active intervals. Fourth, based on the occurrence of DoS attacks, a switching‐like observer and a normal one are respectively proposed to estimate the UGV state, the UAH state, the reference input of the UGV, and the disturbance of the UAH, which are further utilized to design the tracking controller. Fifth, an augmented closed‐loop system consisting of observation errors and tracking error is established and its stability is analyzed by using Lyapunov stability theory.

In this article, the hybrid‐triggered predictive control of cyber‐physical systems (CPSs) under cyber‐attacks is researched. Firstly, considering the unpredictable state of the CPSs, an observer‐based model is constructed, and the predictor is put forward to predict state. Secondly, a hybrid‐triggered scheme is adopted to avoid unnecessary‐data transmission by introducing a hybrid switch mode. Thirdly, the deception attacks and DoS attacks are existed in sensor‐to‐observer (S‐O) and observer‐to‐controller (O‐C), separately. Two types of attack modeling are established based on their characteristics. With the proposed control method, some sufficient conditions are obtained to ensure the input‐to‐state stability (ISS) of CPSs. Finally, the results of simulation examples are received to testify the advantage of developed control strategy.
