This paper discusses the finite-time event-triggered control problem for nonlinear semi-Markovian switching cyber-physical systems under false data injection attacks. The proposed event-triggered scheme effectively avoids network resource waste and establishes a closed-loop system model considering network-induced delay. By analyzing stochastic finite-time stability of the closed-loop system, the solvability conditions for the finite-time controller are established.
This paper addresses the finite-time event-triggered control problem for nonlinear semi-Markovian switching cyber-physical systems (S-MSCPSs) under false data injection (FDI) attacks. Compared with the traditional time-triggered mechanism, the proposed event-triggered scheme (ETS) can effectively avoid network resource waste. Considering the network-induced delay in the modeling, a closed-loop system model with time delay is established in the unified framework. By the use of a mode-dependent piecewise Lyapunov-Krasovskii functional (LKF), stochastic finite-time stability (SFTS) criteria are established for the resultant closed-loop system. Then, some solvability conditions are established for the desired finite-time controller in light of a linear matrix inequality framework. Finally, an application example of vertical take-off and landing helicopter model (VTOLHM) is provided to demonstrate the effectiveness of the theoretical findings.
