“…Therefore the comparison of communication cost is illustrated. As the sampling rate of classical control method is fixed, it causes the communication cost of the classical control method to be much higher than for the STC method [49,50]. We only compare the proposed STC method with the conventional STC method in Figure 12.…”

Abstract:In control systems of power grids, conveying observations to controllers and obtaining control outputs depend greatly on communication and computation resources. Particularly for large-scale systems, the costs of computation and communication (cyber costs) should not be neglected. This paper proposes a self-triggered frequency control system for a power grid to reduce communication costs. An equation for obtaining the triggering time is derived, and an approximation method is proposed to reduce the computation cost of triggering time. In addition, the communication cost of frequency triggering is measured quantitatively and proportionally. The defined cost function considers both physical cost (electricity transmission cost) and communication cost (control signal transmission cost). The upper bound of cost is estimated. According to the estimated upper bound of cost, parameters of the controller are investigated by using the proposed optimization algorithm to guarantee the high performance of the system. Finally, the proposed self-triggered power system is simulated to verify its efficiency and effectiveness.

“…Transmission strategies are the main research objectives for CPSs and many control methods have been taken into consideration, such as round‐robin and hybrid transmission strategies, 20 the acknowledged (ACK) and requested (REQ) signals 23 . Adhering to the principle of saving network resources, the transmission mode transforms from time trigger 24 to event trigger 25‐27 . The event trigger is adopted in References 28‐31 where the control signal only renews when an event is triggered.…”

Event‐triggered controllers are designed for cyber‐physical systems (CPSs) with multiple transmission channels in this article, including two cases: with and without denial‐of‐service (DoS) attacks. Through the design of switching controller and the use of linear matrix inequality‐based (LMI‐based) method, the global exponential stability of the CPSs with multiple transmission channels in both cases are proved, and the relationship of parameters of DoS frequency and duration with the sampling period is established. An example of unmanned ground vehicle under DoS attacks is given to show the effectiveness of the proposed control method.

“…Unfortunately, this strategy may still cause unnecessary communication and consumption of computing resources. To further address this issue, various ETC strategies were proposed [14][15][16][17][18][19], where the data will be broadcasted depends whether the pre-designed event-triggering condition is met or not. For example, the authors in [14] proposed a centralized output feedback ETC to achieve consensus of linear MASs.…”

“…By applying the centralized ETC protocol, leader-following consensus issue of MASs with different structure of topologies was investigated in [15]. Wang et al [16] introduced a centralized ETC scheme with internal dynamic variables to investigate the consensus issue of MASs. It is noteworthy that centralized ETC approaches require information from all agents of MASs, which may cause unnecessary waste of resources.…”

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.
