| 摘 要： | 讨论了连续时间混沌系统的精确同步问题.将系统线性项与非线性项分离,并将响应系统的部分非线性项由驱动系统替代来实现同步.由于可供替代的部分具有较大的灵活性,从而使该方法在具体操作中灵活性更大,实用性更强.以Lorenz系统为例的数值实验证实了该方法的有效性和鲁棒性.另外,在数值实验中考虑了噪声的影响,结果表明,该方法具有强的抗噪声能力.

| Abstract: | The complete synchronization of a chaotic time-continuous system is investigated,and synchronization is achieved via appropriate separation of the chaotic system and replacement of some nonlinear terms. Since the terms,which can be replaced,are always excessive,the method is flexible in the choice of drive signals.The effectiveness and robustness of the method are verified by the numerical results,and the influence of noise on this kind of synchronization is also studied numerically.It is found that the synchronization isn't sensitive to noise. |
