Finite-time chaos synchronization of the delay hyperchaotic Lü system with uncertain parameters

Abstract

This paper deals with the finite-time chaos synchronization of the delay hyperchaotic L\u00fc systen with uncertain parameters. Based on the finite time stability theory, a control law is proposed to realize finite- time chaos synchronization for the delay hyperchaotic L\u00fc systen with uncertain parameters. The controller is simple, robust and only part parameters are required to be bounded. Numerical simulation results are given to demonstrate the effectiveness of the proposed finite-time chaos synchronization scheme.
