基于积分观测器实现一类受扰混沌系统的同步

在系统参数和系统输出同时受扰的情形下，基于积分观测器的方法，实现了一类不确定混沌系统的同步.首先利用Lyapunov 稳定性理论，给出了混沌系统同步所需的充分条件，此条件可以快速地实现驱动系统与响应系统的同步，然后结合Schur补定理，将此条件转化为求解线性矩阵不等式组.最后，借助Matlab软件包中的LMI工具箱，通过对受扰MLC电路系统的同步数值仿真，证实了该方法的有效性.

Robust synchronization of a class of chaotic systems based on integral observer method

Using the integral-observer approach, chaos synchronization is achieved for a class of chaotic systems when both the parameters and the output of the system are perturbed. Based on Lyapunov stability theory and LMI technique, we give the sufficient criterion, which can make the drive system and the response system globally exponentially synchronized. In the end, we take MLC chaotic system as an example to verify the effectiveness of the proposed method.
