| 摘 要： | 用Ｌｏｒｅｎｚ系统对两种混沌同步方法－变量替换法和变量反馈法进行了数值研究。结果表明用单变量反馈可混沌同步，并比变量替换法有较快的收敛速率和较高的同步稳定性。用单变量反馈法同步的混沌系统同样可以用于通讯，且结构简单，便于应用。

| Abstract: | Two techniques of chaos synchronization, variable substitution and variable feedback, are applied to Lorenz systems. Numeric simulation shows that synchronization of chaotic systems can be achieved by feedback of only one variable. Using feedback approach, convergence rate and stability are better than that obtaied by variable substitution method. The systems synchronized by feedback of one variable can also be used to secure communications. The technique is more convenient in practical use. |
