Finite-Time Stability Under Denial of Service

Finite-time stability of networked control systems under Denial Service (DoS) attacks are investigated in this paper, where the communication between plant and controller is compromised at some time intervals. Toward goal, first an event-triggered mechanism based on variation rate Lyapunov function proposed such that closed-loop system remains finite-time stable (FTS) same time, amount data exchange network reduced. Next, vulnerability presence DoS evaluated sufficient conditions duration frequency obtained to assure attack no assumption terms following a certain probabilistic or well-structured periodic model considered. Finally, efficiency approach demonstrated through simulation study.
