本篇論文首先探討動載懸掛系統之渾沌同步現象及同步時的暫態反應。當討論系統的同步現象時，利用李亞普諾夫指數來判斷系統發生同步時的臨界值。可以發現在大部份的同步現象均可以利用此方法來判斷，但在某些的條件之下其還是存在一個誤差。其次將探討自治與非自治系統的同步現象，可很容易發現兩系統不能完全同步，所以將探討它們之間的相位同步現象。又討論渾沌同步在實際秘密通訊上的應用。
最後將探討幾個反控制渾沌的方法，如外加定力矩、外加週期力矩、外加週期脈衝、延遲迴授控制、適應控制。這些反控制的方法可以使系統的週期行為反控制為渾沌現象。

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.
