Resilient Memory Event-Triggered Finite-Time Bounded for Networked Control Systems with Multiple Cyber-Attacks

Abstract

This work is concerned with the resilient memory event-triggered finite-time bounded of networked control systems (NCSs) with actuator faults and multiple attacks. The deception and denial-of-service (DoS) attacks are modelled in a unified framework within multiple attacks. Firstly, the purpose of memory event-triggered scheme (METS) is utilized to release certain packets to establish new events contrasting with the existing event-triggered method. This approach not only enhances the system dynamics but also improves the flexibility. The attack strategy is then developed to consider the security issue of NCSs. A random variable is presented to relate multiple attacks where the malicious signals are injected by adversaries. By utilizing Lyapunov stability theory and linear matrix inequalities (LMIs), a sufficient condition is constructed to attain the exponentially mean-square finite-time bounded of NCSs subjected to multiple attacks. In the end, a satellite system is simulated to illustrate the efficacy of the proposed METS.
