| 摘 要： | 在本文中,将介绍一种基于相位控制的混沌同步方法,就是在相空间中当收发两端的相轨到达事先设置的一些庞加莱截面时,对系统收发两端的相位差和状态差进行取样,经过将取样结果进行处理后,对系统接收端的相位和状态进行调整以达到整个混沌同步系统的同步目的.在文中,将利用蔡氏电路作为系统模型,对这种混沌同步方法进 行详细的研究,同时也将给出系统的计算机仿真结果.

| Abstract: | In this paper,we will present a kind of chaotic synchronization method using phase control.In this method,the phase and state errors between the sending and the receiving ends are sampled when the traces in the phase space of sending and receiving ends reach the Poincare planes set in advance.After processing,the sampled data are used to control the phase and state of receiving end so that the system gets synchronization.In this paper,the Chua's circuit will be used as system model to study this kind of synchronization method in details,and we also present the simulation results of the system. |
