Adaptive event-triggered control for networked interconnected systems with cyber-attacks

Abstract

This paper investigates the secure adaptive event-triggered controller design for networked interconnected systems (NISs) with cyber-attacks. Firstly, an adaptive event-triggered mechanism (AETM) with dynamic threshold parameter is adopted to economize the limited network bandwidth which takes the abrupt data into consideration. A model of cyber-attacks is established for NISs with consideration of the malicious cyber-attacks. On account of the model of cyber-attacks and AETM, a mathematical model of NISs is established. For the built system, the sufficient condition for the asymptotic stability of the system is obtained by making use of Lyapunov stability theory and linear matrix inequality (LMI) technique, and the design algorithm of the controller is proposed. Finally, a simulation example is given to verify the validity of the theoretical results.
