中文摘要：

针对一类复杂网络混沌系统,基于观测器方法设计了一个非线性观测器。当系统状态的非线性项满足一定条件时,可以使观测器的状态按照目标系统轨道演化,所设计的控制器简单且易于实现。结果表明一定条件下复杂网络混沌系统是非线性观测器混沌同步的。

英文摘要：

The paper studied the synchronization problem of a class of complex networks chaos systems designing an nonlinear observer with a controller based on observer approach. When nonlinear parameters of the system meet certain conditions,the observer can be made to evolve around the target orbit and the designed controller is easy to operate. The study illustrated that complex networks systems is in synchronization under proper conditions.
