This paper investigates the estimate-based adaptive neural secure control method for nonminimum-phase nonlinear networked control systems (NNCSs) under hybrid attacks via dynamic event-triggered scheme. Hybrid attacks such as denial-of-service (DoS) attacks and false data injection (FDI) attacks are assumed to occur in the sensor-to-controller (STC) channel and controller-to-actuator (CTA) channel. When only the system output is obtained, a sampled-data observer is introduced to estimate unknown system states. In order to improve the utilization of communication bandwidth under DoS attacks, a dynamic event-triggered scheme (DETS) is proposed to save network resources. An event-triggered output feedback controller is designed by utilizing neural network (NN) to approximate FDI signals. Based on the proposed dynamic event-triggered control strategy, the selections of the sampling period and the observer gain are derived to ensure the boundedness of the control systems. At last, the efficiency of the control strategy is verified by a numerical example.

In this paper, the finite-time synchronization (FTS) of semi-Markov neural networks (S-MNNs) with time-varying delay is presented. According to the Lyapunov stability theory, a mode-dependent Lyapunov-Krasovskii functional (LKF) is constructed. Compared with the traditional static event triggered scheme (ETS), a dynamic ETS is adopted to adjust the amount of data transmission and reduce the network burden. By using the general free-weighting matrix method (F-WMM) to estimate a single integral term, a less conservative conclusion is proposed in standard linear matrix inequalities (LMIs). Finally, under the comparison of the static ETS and the dynamic ETS, a simulation example verifies the superiority of this method.

The adaptive technique and sliding-mode algorithm (SMA) for observer-based fault tolerant control is discussed with dynamic event-triggered scheme (DETS) in this article. Both the actuator and communication faults are considered, which implies that the inputs of system and controller are unreliable. Moreover, the switched DETS for controller-actuator channel is proposed to reduce bandwidth usage and actuator action frequency, which is different from the traditional event-triggered strategies. To deal with communication faults, which can be described as packet losses, the closed-loop system is modeled as a stochastic system. The SMA-based observer is designed to estimate system states, which lays the foundation for the design of control algorithm to mitigate the effects of faults and DETS. Then, a novel observer-based adaptive sliding-mode control (SMC) law based on hyperbolic tangent function is proposed to guarantee the stochastic globally uniformly ultimately boundedness and reduce chattering. At last, the proposed DETS and observer-based adaptive SMC law are applied into a robotic arm to illustrate the validity.

This paper presents a dynamic event-triggered output feedback controller for networked control systems under Markovian deception attacks. A dynamic event-triggered scheme is applied to curtail redundant sensor-to-observer data transfers. Given the prevalence of deception attacks in network signal transmission, these are modeled by a Markov process, and construct an augmented system. Utilizing Lyapunov stability theory, conditions are established for the system's asymptotic stability. Controller gains and event-triggering parameters are derived through the solution of linear matrix inequalities. Simulation results substantiate the controller's effectiveness in countering the impacts of network attacks on the NCSs.

This paper deals with the distributed H-infinity-consensus state estimation problem for a class of discrete time-varying systems with integral measurements over sensor networks. The addressed target plant has its output modeled as integral measurement so as to account for the interval time taken for sample collection. The signal transmissions between an individual sensor node and its neighboring nodes are first scheduled by a dynamic event-triggered scheme (ETS) for the purpose of energy saving, and such transmissions are further prone to hybrid cyber-attacks (comprising denial-of-service and deception attacks). A distributed estimator is constructed for each node by using the available information from itself and its neighboring nodes such that the estimation error dynamics achieves the prescribed H-infinity-consensus performance in mean square sense. A local performance analysis method is developed to establish sufficient conditions that ensure the existence of the desired distributed estimators, and the corresponding estimator gains are then obtained by solving certain recursive matrix inequalities. The effectiveness of the proposed distributed estimation algorithm is illustrated through extensive simulation studies, where comparative experiments are conducted on time-triggered scheme, static ETS and dynamic ETS.

This paper investigates the dynamic event-triggered dissipative consensus for two-time-scale semi-Markov jump multi-agent systems with external disturbances and false data injection attacks. Two-time-scale semi-Markov jump models are established to describe the two-time-scale phenomenon and the abrupt change of system parameters. Moreover, a dynamic event-triggered scheme in which the threshold parameter can be adjusted appropriately with the state fluctuations is adopted to reduce unnecessary data transmission and make more rational use of limited network resources. Some sufficient conditions rely on the Lyapunov analysis method are developed to ensure the (Q, S, R)-dissipative consensus can be achieved. eventually, a numerical example is presented to corroborate the effectiveness of the obtained theoretical results.
