Finite-time Synchronization of Large-scale Hyper Chaotic Systems with Parametric Uncertainties and Time-varying Delay

Qiaoping Lia,b,*, Sanyang Liua, Li Gea,b

ABSTRACT:     In this paper, the finite-time synchronization of large-scale hyper chaotic systems with parametric uncertainties and time-varying delay is investigated. Based on Lyapunov stability theory and finite-time control technique, a suitable time-delay state feedback controller is designed, and a sufficient condition of finite-time synchronization is put forward. Finally, the numerical simulation is presented to illustrate the applicability and effectiveness of the proposed method.
