Periodic event-triggered resilient control for cyber-physical systems under denial-of-service attacks

Observer-based adaptive secure control with nonlinear gain recursive sliding-mode for networked non-affine nonlinear systems under DoS attacks

“…Thus, it is sensitive for the controller to the perturbation of the parameters. In this paper, we define the recursive sliding surfaces (25), (31) and (37) for building error relationship among all subsystems to expand the range of control parameters.…”

“…According to (42), θ i , ρ i and h i are ultimately bounded. From(31)(33) and(36),x i , α i and z i are also bounded. In addition, due to the bound of ρ i and ρ i , it follows thatρ i is bounded.…”

Robust event‐triggered model predictive control for cyber‐physical systems under denial‐of‐service attacks

“…Based on the general DoS model, several studies have been presented for linear systems, 14,15 nonlinear systems, 16 CPSs with multiple transmission channels, 17 and CPSs with event-triggered control strategy. 18,19 However, the resilient control methods of the aforementioned works mainly focus on the transmission times scheduling and input-to-state stability (ISS) framework. There have been few theoretical studies appeared on control methodology to guarantee the control performance under DoS attacks, especially when the state and input of the physical plant are subject to hard constraints.…”

Design of sampled-data controllers for the synchronization of complex dynamical networks under controller attacks

“…On the other hand, from the recent situation of growing communication technology, it can be understandably expected that the importance of security against cyber-attack has been emphasized [33][34][35][36][37][38][39][40][41][42]. Adversaries maliciously modified the data by exploiting the vulnerabilities of networks, which has degraded or destroyed the stability and performance of the system.…”

“…Thus, to develop criteria with prevention measure against cyber-attacks is a major concern of scholars [38,39]. In [40], H ∞ observer-based periodic event-triggered controller for the control of a class of cyber-physical systems was designed under consideration of DoS attacks where the designed controller maximized the frequency and duration of the DoS attacks. In [41], distributed event-triggered H ∞ filters were designed on sensor networks in the presence of sensor saturations and randomly occurring cyber-attacks.…”
