dc.description.abstract	一般認為在心臟動力學行為由規律演變至混沌的過程中會有週期倍增的現象， 稱為倍週期(Period-doubling)。而交替震盪的現象(Alternans) 正是倍週期的開始，因此成為了預測心律不整的重要指標。我們研究了Logistic Coupled Map Lattice 空間上的交替現象，並使用r+r-回饋控制方法進行局部區域控制。我們發現處於過渡狀態交替現象的區域更容易被抑制，也適合做為完全抑制交替現象的起點。最後我們提出了動態控制策略，以控制關鍵區域達到完全抑制空間上的交替現象，大約只需要10% 的控制比例。	zh_TW
dc.description.abstract	It is generally believed that there is a phenomenon of period-doubling when cardiac rhythm undergoes a transition from periodic to chaotic dynamics. Cardiac alternans, which is a period-2 oscillation, has become an important indicator of arrhythmia prediction. In this thesis, we study the spatial alternans in the Logistic Coupled Map Lattice and aim at suppressing local alternans by using the r+r- feedback control method. We find that the transition state of the alternans is easier to be suppressed, and it can serve as the starting point for suppressing whole spatial alternans. Finally, we propose a dynamic control strategy to achieve the suppression spatial of alternans by using only about 10% of the control ratio.	en_US
