Dynamic Event-Triggered H_∞ Fault-Tolerant Control of NCSs under Dual-Channel Deception Attacks

This paper introduces a dynamic event-triggered H<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</inf> fault-tolerant control method for networked control systems (NCSs) with actuator faults under dual-channel deception attacks. Firstly, a novel control framework for NCSs is constructed by mathematically describing actuator fault, external disturbance, deception attack and network delay. A novel dynamic event-triggered mechanism is suggested for saving communication resources. Then, through the construction of Lyapunov-Krasovskii functional, the sufficient condition to assure that the system is asymptotically stable and the collaborative design approach for the H<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</inf> controller and dynamic event trigger are further provided. Finally, the validity and advantages of the suggested control strategy are illustrated through an arithmetic example.
