摘要
提出了一个新的四维分段超混沌Chen系统,该系统含有六个参数,三个非线性项,借助Lyapunov稳定性定理分别用混合同步和非线性反馈控制,给出了系统在初值条件下实现自同步的充分必要条件及控制参数的变化范围;运用Matlab进行数值仿真,给出了系统的同步相图和误差图,驱运系统和响应系统能够很好地达到同步.
The piecewise four-dimensional continuous autonomous chaotic system is studied. The new system contains six system parameters and three quadratic cross-product terms. Based on Lyapunov stabilization theorem,and hybrid synchronization and nonlinear feedback control method, the sufficient conditions and range of the controller ＇s parameter for self-synchronization of chaotic systems are derived. Matlab simulation results show the phase diagrams and error between driver system and response system. The orbit of the response system is exactly the same as that of the driver system. The error signals approach zero smoothly.
