Extended dissipative performance for a complex dynamical networks based on adaptive event‐triggered filter method subject to hybrid attacks

Abstract

SummaryThe challenge of adaptive event‐triggered based filter design for complex dynamical networks with time‐varying coupling delays under hybrid attack is studied in this research. A new model of complex dynamical networks with input constraints, involving denial‐of‐service (DoS) attack, replay attack, and deception attack is designed. An adaptive event‐triggered scheme is applied to filter design, which adaptively modifies the communication threshold level in order to reduce the effect of the transmission load. By using Lyapunov theory and inequality techniques, a novel necessary condition is proposed that guarantees mean‐square asymptotically stability with extended dissipative performance. The proposed filter parameters are then given an explicit expression, which is solved using a set of linear matrix inequalities. Finally, two numerical results are presented to demonstrate the validity of the theoretical result suggested.
