摘　　要：针对由Aiminchen等人最近提出来的一个新的超混沌系统—超混沌Lü系统的同步问题展开研究.对两个恒同的超混沌Lü系统,分别给出了它们在线性耦合和非线性耦合情形下在全局范围内实现同步的充分条件,用Lyapunov方法从理论上证明了结论,并用数值仿真验证了理论结果.This paper analyzed the synchronization of a new hyperchaotic system-hyperchaotic Lu system introduced by Aimin chen et al. Two sufficient conditions for the global synchronization of two identical linearly and nonlinearly coupled hyperchaotical Lu systems were given respectively. The conclusions were proved theoretically based on Lyapunov method. Finally, numerical simulations were given to demonstrate the feasibility of the theoretical conclusion.
