“…The main differences from this work compared to previous studies can be summarised: A combination of event‐triggered control (ETC) and

H_{\infty}

LFC control has been studied while preserving the desired control performance and improving the communication efficiency. Different from the recently reported study [20] without involving the DoS attacks, the proposed MPETC scheme considers the DoS attacks. Moreover, different from [21], in which the event‐triggered communication scheme only depends on the quality‐of‐service of communication network, since the predictive networked control (PNC) is also considered in this paper, higher transmission efficiency can be expected.…”

In this study, a novel H ∞ predictive event-triggered load frequency control has been developed for a hybrid power system with renewable energy sources (RESs) to deal with denial-of-service (DoS) attacks, where the DoS duration (the time attack lasts) are boundless. A predictive event-triggered transmission scheme is built for the multi-area hybrid power systems under DoS attacks to reduce the load of network bandwidth while maintaining adequate levels of performance. Therefore, an observer-based predictive controller is developed in the presence of both external disturbances and DoS attacks by formulating the LFC problem as a disturbance attenuation issue. In the proposed method, a hybrid power system with RESs is used to achieve novel and better security strategies. Based on the new model, sufficient conditions are obtained using the Lyapunov stability theory to ensure a stable multi-area hybrid power system with a prescribed H ∞ performance. Moreover, an algorithm is provided to obtain the control strategy of DoS attacks. Finally, the simulation of a hybrid power system with RESs is presented to demonstrate the effectiveness of the proposed method in dealing with the DoS attacks.

“…In [13], the static output frequency control issue for timedelay power systems is investigated, in which electric vehicles are considered in control strategy to suppress fluctuations of frequency induced by load changes. Compared with some ETMs with constant triggering threshold parameter, an adaptive event-triggered LFC issue of power systems is developed in [14] by designing a dynamic triggering threshold. Different from the above ETMs based on sampled data (also called discrete-time ETM), a switching ETM [16] between a waiting period and a continuous-time ETM is utilized in frequency regulation for power systems with time-varying communication delays in [15].…”

This article focuses on H∞ load frequency control (LFC) of multi-area power systems with cyber-attacks and communication delays by a memory-event-triggered mechanism (METM). The dynamics of power system components, such as governor, turbine and power generator, are imitated by some circuit systems. To save the precious network bandwidth, a METM is constructed to decide which measured data should be transmitted as the control signal. In contrast to some memoryless ETMs, the proposed METM uses historic data over a fixed period. To guarantee no Zeno behavior, a positive constant time is waited after each trigger happens. By treating the exchanges of tie-line power between the ith control area and other areas as exogenous disturbances, a novel decentralized distributed delay system is modeled to represent the decentralized H∞ LFC of a multi-area power system under the proposed METM with deception attacks and communication delays. By selecting a Lyapunov-Krasovskii functional (LKF) based on the distributed delay terms, new sufficient criterions are obtained to co-design the H∞ LFC controller and triggering parameters for power systems against deception attacks. Finally, the advantages of the presented method is shown via an illustrative case. Index Terms-Memory event-triggered mechanism, load frequency control, cyber-attacks, power systems.

“…In recent years, the event-triggered mechanism has been applied in various systems widely, such as network control systems [21], [22], multi-agent systems [23], [24], T-S fuzzy models [25], nonstrict-feedback systems [26], [27], and so on. Meanwhile, rich results with respect to event-triggered control have been achieved [28]- [32]. In [28], an adaptive event-triggered method is discussed to get a balance between the number of the transmitted information and the dynamical performance.…”

Event-Triggered Integral Sliding Mode Anti-Disturbance Control for Nonlinear Systems Via T-S Disturbance Modeling

Under the framework of event triggering, this paper discusses a novel integral sliding mode (ISM) anti-disturbance algorithm for a class of nonlinear systems with mismatched disturbances. For the sake of describing more irregular disturbances, T-S fuzzy disturbance models are imported by choosing different basis functions and the corresponding disturbance observer (DO) is then put forward to realize the estimation of unknown disturbances. By utilizing the trigger threshold condition with the estimation information, both the integral sliding surface (ISS) and the event-triggered ISM controller are designed for compensating mismatched disturbances. It is guaranteed that the state trajectories can reach the ISS within a pre-designed finite time. Moreover, not only the system stability, but also the favorable tracking performance and the boundedness of the minimum trigger interval are simultaneously be achieved. Finally, the simulation results of an A4D aircraft model further embody the effective of designed control algorithm.
