中文摘要：

讨论了一类具有比例时滞和非线性耦合的复杂网络指数型同步问题。基于时间变量指数变换可把比例时滞转化为常数时滞的方法,通过构造李雅普诺夫泛函和设计合适的控制器,建立驱动-响应网络指数型同步的充分条件。最后通过数值模拟验证了结果的有效性。

英文摘要：

The exponential synchronization problem for a class of complex networks with proportional delays and nonlinear coupling was discussed. Based on the approach of exponential transformation of time,sufficient conditions for exponential synchronization of drive-response networks were established by constructing proper Lyapunov functional and designing suitable controller. Finally,a numerical simulation was given to illustrate the effectiveness of the results.
