摘　　要：针对Lorenz超混沌系统,以稳定性理论为基础,提出一种超混沌系统的混合同步方法,给出Lorenz超混沌系统实现自同步的充分条件以及控制律参数的取值范围,构建Lorenz和Chen超混沌系统异结构同步的数学模型,并对模型进行数值模拟.数值模拟结果表明,该方法能够实现同、异结构超混沌系统精确同步.Synchronization of Lorenz hyper-chaotic systems is studied. Based on the Lyapunov stability theory, a combined synchronization method of hyper-chaotic systems is presented; the sufficient conditions and range of the controller＇s parameter for self-synchronization of Lorenz hyper-chaotic systems are derived and carefully proved. And the mathematic model of synchronization with different structure of Lorenz and Chen hyper-chaotic systems is given. The numerical simulations also illustrate the main theoretical results and the maneuverability of the obtaining method in this paper.
