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.
By constructing the fast sliding mode controller, the finite time synchronization of the chaotic system is realized. It is pointed out that many chaotic systems can achieve the complete synchronization between the drive system and the response system in a limited time through the fast convergence finite-time controller after the state transformation, The simulation of Chen chaotic system and fourth-order cellular neural network hyperchaotic system are taken as examples to show that the finite-time controller not only has good performance but also has strong robustness.
