SQCF系统的非线性同步控制

Nonlinear Synchronization Control for SQCF System

针对SQCF(Simplest Quadratic Chaotic Flow)系统,利用非线性同步控制方法设计了控制器,通过该方法实现了SQCF系统的自适应同步与Genesio系统的异结构同步.与传统的混沌同步方法相比较,该方法不需要计算条件Lyapunov指数,因此比较简单、有效,并利用数学软件给出数值模拟.通过理论分析和数值仿真表明该方法的有效性并且该方法对于其它的混沌系统也是适用的.

Via nonlinear control method two controllers are designed for SQCF system （Simplest Quadratic Chaotic Flow） in this paper. The proposed method is presented to study the adaptive synchronization of SQCF system and the synchronization between SQCF system and Genesio system. Compared with the traditional approaches, this proposed method is much Simpler and effective because the Lyapunov exponents are not required to calculate. The math-ematical software is used to simulate. Both theoretical analysis and simulation result show the effectiveness for this method and this method can also be used for other chaotic systems.
