Design of H_∞ Synchronization Controller for Chaos System and Its Application to Security Communication System

摘要

In this paper, a robust H_∞ controller is proposed for the chaotic synchronization system with time-delays, parametric uncertainties as well as noise disturbance. The delay independent stability criteria is presented for error system based on Lyapunov method and linear matrix inequality (LMI) formulation. The simulation results show that this synchronization control scheme is applicable for security communication system well.
