摘要: | 本篇论文首先探讨动载悬挂系统之浑沌同步现象及同步时的暂态反应。当讨论系统的同步现象时,利用李亚普诺夫指数来判断系统发生同步时的临界值。可以发现在大部份的同步现象均可以利用此方法来判断,但在某些的条件之下其还是存在一个误差。其次将探讨自治与非自治系统的同步现象,可很容易发现两系统不能完全同步,所以将探讨它们之间的相位同步现象。又讨论浑沌同步在实际秘密通讯上的应用。 最后将探讨几个反控制浑沌的方法,如外加定力矩、外加周期力矩、外加周期脉冲、延迟回授控制、适应控制。这些反控制的方法可以使系统的周期行为反控制为浑沌现象。 In this thesis, we first study the chaotic synchronization phenomena of the suspended track with moving load system, and the transient response of chaos synchronization. The Lyapunov exponent is utilized to prove the chaos synchronization but under certain conditions it is more complicated. Next, we study the synchronization of autonomous and nonautonomous system. We find that slave systems can not be synchronized with mater system no matter how large is . Next, the phase synchronization between them will be studied. An application of chaos synchronization, secure communication, is presented. Finally, in order to increase the chaos phenomena, we use anticontrol. Constant torque, periodic torque, periodic impulse signal, time delay function, the adaptive control are used successfully to control the state from order to chaos. |
