Asynchronous event-triggered control for switched T-S fuzzy systems under dual-channel hybrid cyber attacks

This article presents an asynchronous event-triggered scheme for switched Takagi-Sugeno (T-S) fuzzy systems against dual-channel hybrid cyber attacks. Different from existing results, both sensor and controller channels are subjected to aperiodic denial-of-service attacks and random false data injection attacks. To efficiently utilize dual-channel network communication resources while resisting hybrid attacks, two resilient event-triggered mechanisms (ETMs) are constructed. Considering asynchronous ETMs and hybrid cyber attacks, the time-delay switched T-S fuzzy system is derived by utilizing model transformation methods. Thereby, the stability conditions are derived by utilizing multiple Lyapunov functions technique, and slack matrices are introduced to further relax the conditions. Finally, two examples are given to demonstrate the effectiveness of the developed event-based security control strategy.
