Adaptive event-triggered synchronization control for complex networks with quantization and cyber-attacks

Abstract

This paper investigates the adaptive event-triggered synchronization control problem for a class of complex networks with quantization and cyber-attacks. For reducing the burden of communication and computation, an adaptive event-triggered scheme and a logarithmic quantizer are both introduced. Firstly, considering the effect of adaptive event-triggered sampling, quantization and cyber-attacks, a novel synchronization error model is established. By using Lyapunov functional method, some sufficient conditions are derived to guarantee the asymptotic stability of the augmented synchronization error system. Moreover, the co-design of the controller and adaptive event-triggered scheme are also solved in terms of solving the solution of linear matrix inequality(LMI). Finally, a numerical example is exploited to show the effectiveness of the proposed method.
