两个不同不确定混沌系统的一致最终界鲁棒同步

Robust synchronization with uniform ultimate bound between two different chaotic systems with uncertainties

Jianping Cai, Zhengzhong Yuan

摘要:

设计了自适应控制器来同步两个具有不确定性的混沌系统,这些不确定性包括未知参数、内部和外部扰动。利用李雅普诺夫稳定性理论证明了在一定条件下,即使事先不知道不确定性的界,驱动-响应系统也能以一致的最终界实现同步.所设计的控制器仅包含系统的反馈项和部分非线性项,易于实现。以Lorenz系统和Chen系统为例验证了该方法的有效性。仿真结果也表明,该控制器对各种干扰具有良好的鲁棒性。

英文摘要:

Adaptive controllers are designed to synchronize two different chaotic systems with uncertainties, including unknown parameters, internal and external perturbations. Lyapunov stability theory is applied to prove that under some conditions the drive-response systems can achieve synchronization with uniform ultimate bound even though the bounds of uncertainties are not known exactly in advance. The designed controllers contain only feedback terms and partial nonlinear terms of the systems, and they are easy to implement in practice. The Lorenz system and Chen system are chosen as the illustrative example to verify the validity of the proposed method. Simulation results also show that the present control has good robustness against different kinds of disturbances.
