摘　　要：目的混沌同步在很多领域中有着重要应用,它成为研究非线性科学的一个重要课题,受到极大的关注。主要比较和分析几类混沌同步的方法及其基本原理,为相关的研究提供引导和参考。方法通过分析和数值模拟,比较P-C同步和主动-被动同步这两种同步方法。结果 P-C同步的方法需要将系统进行特定的分解,实际操作中有较大的局限性;主动-被动同步方法可以自由选择驱动信号,使用起来更具有普遍性和灵活性。结论两种同步方法在通信设备的设计中都被广泛的应用,主动-被动同步方法更为广泛和便捷。Objective Because of its important application in many fields,synchronization in chaotic systems has been a theme in nonlinear sciences and received considerable attention.The main methods and basic theories of chaos synchronization were compared and analyzed to support related researches.Methods Through analysis and numerical simulations,the two synchronization methods of P-C Synchronization and Active-Passive Synchronization were compared.Results P-C Synchronization method requires specific decomposition of the system which has great limitations;Active-Passive Synchronization can choose the driving signal freely,so it's very general and flexible.Conclusion The two synchronization methods have been widely used in the design of communication devices,and the Active-Passive Synchronization is more extensive and convenient to use.
