Dynamic event-triggered H∞ control for switched T-S fuzzy systems under multiple cyber attacks

This article studies the dynamic event-triggered H-infinity control problem for switched Takagi-Sugeno (T-S) fuzzy systems against multiple cyber attacks. A new multiple cyber attack model is established by considering random false data injection attacks and aperiodic denial-of-service attacks. Then, to further efficiently utilize network communication resources, a dynamic event-triggered mechanism (ETM), which includes a nonnegative dynamic variable, is constructed. Furthermore, the time-delay switched T-S fuzzy system considering dynamic ETM and multiple cyber attacks is derived by utilizing model transformation methods. Moreover, sufficient conditions for globally asymptotically stability and H-infinity performance are derived by utilizing multiple Lyapunov functions and average dwell time method. Finally, an example is provided to validate the effectiveness of dynamic ETM.
