摘　　要：本文将统一混沌系统同时作为同步系统的驱动系统和响应系统,在已确定驱动系统方程的情况下,利用混沌同步的三种方法:PC激活控制法、反馈法、Lyapunov直接法,去构造响应系统方程,并将构造的响应系统以L¨u为例,从理论和数值上进行了分析,又根据Lyapunov稳定性理论,以L¨u系统为例得出两个统一混沌系统达到同步的充分条件,并通过数值模拟验证了所给同步方案的有效性。Unity chaotic system is served as drive system and response system in synchronization system simultaneously. When the drive system is certain, response system is established by using three constructing ways of chaos synchronization： PC activating control, feedback, Lyapunov direction. Based on the response system, an analysis is made theoretically and numerically. According to the Lyapunov stability principle, sufficient condition can be obtained to make Lfi system synchronization and verified to be efficient by numerical simulation.
