“…In this case, the network utilization of the provided method is compared with previous work (Torabi et al, 2021). As noise and disturbances were not considered in Torabi et al (2021) and in order to provide a similar experimental condition, these effects were not taken into account. The initial conditions of the system are set to x 1 p ( 0 ) = [ 6 , 6 ] T and x 2 p ( 0 ) = [ 6 , 6 ] T .…”

“…Despite the beneficial features that NCSs provide, some security issues are affecting the performance of the control system or even causing it to malfunction (Bansal and Mukhija, 2020; Guo et al, 2021; Wang et al, 2022). The development of stability analysis and controller design for cyber–physical systems, particularly networked control systems (NCSs), has increased rapidly over the past decade due to a wide variety of industrial applications (Bahreini et al, 2019, 2021; Bahreini and Zarei, 2020; Ghorbani et al, 2021; Hassani et al, 2019; Kargar et al, 2019; Li and Chen, 2019; Li et al, 2019; Saeedi et al, 2021; Tian, 2021; Torabi et al, 2021). Therefore, cyber-security issues should be considered in the analysis and synthesis of such systems.…”

“…It is illustrated that by considering DoS attacks and networked imperfections, the proposed method guarantees the stability of the overall NCS. Recently, we proposed a decentralized resilient observer-based output-feedback controller for the NCSs (Torabi et al, 2021). However, in that work, a time-triggered protocol that uses high resources from the network is employed.…”

This paper studies the problem of resilient dynamic output-feedback control schemes for continuous-time networked control systems (NCSs). A decentralized hybrid strategy is utilized while network imperfections, external disturbances, and noise are considered. Moreover, during data transmission, a practical denial-of-service (DoS) jamming attack, which periodically disturbs the network channels, is considered. To preserve the network resources, a decentralized event-triggered mechanism is employed to transmit only the sampled signals that are required. It is assumed that outputs and control inputs of each subsystem are transmitted to the corresponding decentralized controllers and actuators, respectively, over the different individual channels based on independent triggering mechanisms. At first, the NCS is modeled as a decentralized hybrid system with exogenous disturbance and noise. Then, sufficient conditions that guarantee the [Formula: see text]-stability of the NCS in the presence of external disturbances and noise, which is resilient to periodic DoS attacks, are provided in terms of the linear matrix inequalities. Finally, sufficient conditions are derived to deal with the time-varying delays. It has been demonstrated that the proposed technique can be effectively applied to a well-known continuous stirred tank reactor (CSTR) as a benchmark example.

“…The emerging of such systems leads to the introduction of an active research area in the analysis and control of critical infrastructures such as transportation systems and power networks (De Persis and Tesi, 2016). Although CPSs benefit from the increased availability and flexibility, but also have some certain limitations such as the packet drop-out (Hu et al, 2019; Kargar et al, 2019), cyber-attacks (Ding et al, 2018; Feng et al, 2020; Ma et al, 2021; Torabi et al, 2021), fading data (Gu et al, 2020), signal quantization (Cao and Liu, 2019; Chang et al, 2019; Yan et al, 2020), communication delay (Moreno, 2009), and faults (Bahreini and Zarei, 2020; Hassani et al, 2019).…”

This paper deals with the problem of regulation and tracking tasks for nonlinear dynamic systems that use a network medium to transmit state measurements. A novel quantized event-triggered fast terminal sliding mode controller (SMC) is proposed to reduce communication resources and computation loads while increase robustness against packet dropout, uncertainties, and disturbances. Then, new criteria are defined for the dynamic quantizer based on the event-triggering error, which increases the accuracy and facilitates the implementation procedures. In practice, delay-free systems are not realistic considerations, thus, their stability is analyzed in the presence of a dynamic quantizer and input delay under the proposed controller scheme. Then, the minimum inter-sampling time is derived, which guarantees the Zeno-free behavior and provides information about the cyber layer bandwidth in cyber-physical systems. Finally, three simulations on an unstable numerical model, the model of an inertia wheel inverted pendulum, and the mass-spring-damper model validate the effectiveness of the proposed methodology.

This article addresses the problem of model predictive control of networked jump systems in the presence of DoS attacks and time delays. In the structural framework of the network predictive control system, we mathematically model the networked jump system by using Markov chains to describe the time delays and a polytope model to describe the jump system phenomenon, considering the properties of DoS attacks and time delays. Based on this, we propose a strategy to lessen the effect of network constraints on the control performance of the system. This strategy involves the corresponding control inputs from the control sequence for real‐time active compensation. It includes adjusting the control sequence application length variation based on the duration of the DoS attacks and time delays at each moment. In addition, we demonstrate the recursive feasibility of the control strategy and the global asymptotic stability of the control system from a theoretical perspective through the Lyapunov stability theory. Finally, the effectiveness of the proposed strategy is verified by simulation arithmetic.
