基于混沌系统运动的有界性，在发送系统模型不确定的情况下，利用多个 3阶扩张状态观测器 (ESO)分别对其各个状态变量进行跟踪，构造出一种不依赖发送系统模型的接收系统，并根据跟踪误差情况对噪声的影响进行补偿，实现了两者之间的同步。以 Lornez为例进行仿真，同步跟踪效果良好。并在此基础上讨论了它在信息传输中的应用。
Based on the boundedness of the chaotic system motion, the state variables of the third order extended state observer (ESO) are respectively tracked with uncertainties of the transmission system model to construct a state independent system Receive the system, and compensate the influence of the noise according to the tracking error situation, has realized the synchronization between the two. Take Lornez as an example to simulate the effect of synchronous tracking. And on this basis, it discusses its application in information transmission.
