基于鲁棒有限时控制的混沌系统的同步

Robust finite time synchronization of chaotic systems

通过构造快速滑模控制器,实现了混沌系统的有限时同步,指出许多混沌系统经过状态变换后,都可以通过快速收敛的有限时控制器在有限时间内实现驱动系统和响应系统的完全同步,并以陈氏混沌系统和四阶细胞神经网络超混沌系统为例进行了系统仿真.结果显示,该有限时控制器不仅具有良好的性能,而且具备较强的鲁棒性.

In this paper, a robust finite time fast sliding mode controller is presented for a class of chaotic synchronization. Using the fast sliding mode controller, many chaotic systems can achieve synchronization with identical response system through state transformation, and Chen's system and hyperchans system of 4th-order cellular neural network are used to demonstrate the obtained results. The results show that the controller possesses the advantage of fast response and robustness.
