“…For the switched systems with partly unstabilizable subsystems affected by jamming attacks, Reference 29 designs an observer‐based controller, but quantization is not discussed. Based on the event‐triggered mechanism, a decentralized quantized controller is proposed in Reference 30 to guarantee the stability of the switched systems with cyber attacks. However, Reference 30 does not relate to unstabilizable subsystems, and a logarithmic quantizer with infinite quantization level is used.…”

This article addresses the problem of stabilizing a continuous-time switched system affected by quantization and denial-of-service (DoS) attacks. The switching is assumed to be slow enough in the sense of combined dwell time and average dwell time, individual modes are assumed to be partly unstabilizable, and DoS attacks are supposed as energy limited by restraining DoS frequency and DoS duration. By introducing a Decision Maker into the system framework and proposing a switching algorithm for the attacked intervals, we simplify the design rules of the controller and divide the system status into four cases.On the basis of approximating the reachable set and analyzing the increasing/decreasing rate of Lyapunov function for each case, the sufficient conditions ensuring the exponential convergence and Lyapunov stability of the closed-loop system are obtained. Two examples are illustrated to demonstrate the effectiveness of the theoretical analysis.

“…Thus, for the case where communication networks exist in both sensor‐to‐controller (SC) channel and controller‐to‐actuator (CA) channel, integrating data quantization, and ETM in both channels is a feasible solution for reducing additional network resources. However, all the related works (for example, References 22–24) employ SETM rather than the better‐performing DETM, which is wasteful from a resource conservatism perspective. Therefore, there is plenty of room for improvement.…”

“…It is worth noting that the LMIs often contain a series of tunning parameters that need to be preset, and their selection greatly affects the feasibility of the LMIs. However, many works configure these parameters based on experience (for example, References 23–25), which inevitably limits the performance of the results. For some simple problems, the empirical design may suffice.…”

This study deals with the problem of dual‐terminal event‐triggered dynamic output feedback (DOF) control for aero engine networked control systems (NCSs) subject to network‐induced delay, external disturbance, and quantization effects. First, we established a generalized mathematical model of the aero engine. Second, a dual‐terminal dynamic event‐triggered mechanism (DETM) was designed to reduce the utilization of the network bandwidth. In addition, a DOF controller with a compensation function was proposed to stabilize the system. By utilizing the Lyapunov‐Krasovskii (LK) method, the stability criteria were determined. Accordingly, the design conditions of the DOF controller and DETMs were presented. Furthermore, based on a genetic algorithm (GA), a parameter tuning method was proposed to obtain the allowable delay upper bound with less conservatism. Finally, some examples were presented to show the effectiveness and superiority of the presented scheme.

“…Jamming attacks were also studied in [20]. Event-triggered communication and decentralized control of switched systems under cyber attacks are analyzed in [21]; in particular, conditions on the dwell-time and the gain for the controller are derived to ensure stability. Other lines of work have studied the robustness properties with respect to attacks of different (discrete-time) optimization algorithms; e.g., [22,23,24].…”

We study the stability properties of the interconnection of an LTI dynamical plant and a controller that generates control signals that are maliciously compromised by an attacker. We consider two classes of controllers: a static output-feedback controller, and a dynamical gradient-flow controller that seeks to steer the output of the plant towards the solution of a convex optimization problem. We analyze the stability of the system under a class of switching attacks that persistently modify the control inputs generated by the controllers. The stability analysis leverages the framework of Hybrid Dynamical Systems, Lyapunov-based arguments for switching systems with unstable modes, and singular perturbation theory. Our results show that the stability of the interconnected system can be preserved when an attack defense mechanism can mitigate "sufficiently often" the activation time of the attack action in any bounded time interval. We present simulation results that corroborate the technical findings.
