Guaranteed Cost Output Feedback Control for Nonlinear Systems via Networks with Adaptive Event-Triggered SCP and Hybrid Attacks

This paper addresses the problem of guaranteed cost output feedback control for a class of networked interval type-2 Takagi–Sugeno (IT2 T-S) fuzzy systems with adaptive event-triggered stochastic communication protocol (AETSCP) scheduling and hybrid attacks. A novel AETSCP scheduling is designed to judge whether or not data are triggered as well as to determine which node transmits data to the controller. Meanwhile, the security problem of hybrid attacks with respect to denial-of-service (DoS) attacks and deception attacks on the system is considered. The quadratic boundedness (QB) technique is employed to depict the closed-loop stability of the concerned networked control systems (NCSs). Two adequate theorems are given based on Lyapunov stability theory for designing the observer-based and dynamic output feedback-based controllers, which guarantee the stability and robust performance of the required system. In the end, a simulation example of the mass-spring-damping system is provided to confirm the effectiveness of the presented control strategy.
