基于输入-输出线性化方法实现混沌系统的同步

本文将非线性控制系统的输入-输出线性化方法应用于混沌系统的同步中。首先对发送系统和接收系统进行适当的坐标变换，分别得到一个具有规范型或类规范型的新系统，再对两个新系统进行比较得到误差系统．然后通过对误差系统进行反馈变换，从而实现混沌系统的输出及其导数的同步．当满足一定条件．还可实现所有状念变量的同步．此方法所需的发送信号仅为标量信号，适于保密通信。对Lorenz系统、Rossler系统的仿真证明了该方法的有效性。

Chaos Synchronization Based on the Input-Output Linearization Method

Chaos synchronization based on the input-output linearization method is proposed. First, proper coordinate transformation is applied to the transmitter system and receiver system and new systems of the canonical form is obtained. Error system is obtained by means of comparing the two new systems, and then synchronizing output of chaotic system and its derivatives is realized via feedback change of error system. When some conditions are satisfied, synchronizing all state variables is realized. The required send signal of this method is only scalar signal, which is fit for secrete communication. Simulation results of Lorenz system and Rssler system manifest the valid of this method.
