即使两个混沌电路之间的完全同步只能达到当系统是相同的，在本文中，我们解决的鲁棒性同步的耦合电路之间的参数失配的情况下的超混沌行为。尤其是。一种基于负反馈的主从控制方案[T. Kapitaniak，Synchronization of chaos using continuous control，Phys.Rev.E50（1994）1642-1644]，并给出了将从系统设计成主系统的观测器的策略。该方法基于主稳定函数的概念，通过一个唯一的标量信号将两个电路耦合。从两个超混沌电路获得的实验结果将被提交，以表明同步发生广泛的电子元件公差的范围内。(C)2009爱思唯尔有限公司版权所有。
Even if complete synchronization between two chaotic circuits can be reached only when the systems are identical, in this paper we address the robustness of synchronization in the presence of parameter mismatches between the coupled circuits in the case of hyperchaotic behavior. In particular. a master-slave scheme based on negative feedback [T. Kapitaniak, Synchronization of chaos using continuous control, Phys. Rev. E 50 (1994) 1642-1644] is considered and the strategy to design the slave system as an observer of the master is given. With the proposed approach, based on the concept of the Master Stability Function, the two circuits are coupled through a unique scalar signal. Experimental results obtained from two hyperchaotic circuits will be presented in order to show that synchronization occurs widely in the range of electronic component tolerances.
