时空混沌的滑模变结构控制同步

Synchronization of discrete spatiotemporal chaos by using variable structure control

基于一维的Logistic耦合映像格子模型的时空混沌同步,利用主从拆分同步、非线性耦合、非线性反馈函数等方法,研究了时空混沌的同步问题,提出了离散滑模变结构控制方法,实现了两个全局Henon耦合映像格子系统的互同步,仿真结果证明了该方法的有效性和鲁棒性.

Researches of the synchronization of spatiotemporal chaos was all based upon the model of one-dimensional coupled Logistic map lattice. So a discrete nonlinear sliding mode variable structure approach is presented to implement the mutual synchronization of two globally coupled Henon map lattice system. Numerical simulations demonstrate the feasibility and robustness of the proposed control strategy.
