摘要: | 本论文将依照约瑟芬逊接面RSJ(Resistively ShuntedJosephson Junction)方程式所制成之电子系统,藉由此系统观察由Feigenbaum致使 混沌区间之动力行为情形,进而找寻适当控制该混沌之有效机制。本文以 实际电子系统模拟RSJ模式之运作,并以OGY (Ott,Grebogi,Yorke)的混沌 控制理论为依据,我们首先发现依工程用之OPF(OccasionalProportional Feedback)反馈控制法可以达到最为简便制约Feigenbaum混沌的功能。事 实上,最重要吾人采用一维Return Map的分析,替代原先OGY理论所建议 二维Poincare Map较繁杂的方法。至于如何选择适当之控制参数的技术与 方法等细节,将分别予以详述。 The electronic techniques of controlling chaos in the Resistively Shunted Josephson Junction model(RSJ model) have been investigated. With regard to Feigenbaum route to chaos, we point out that the OGY (Ott,Grebogi,Yorke) method of controlling chaos can be simplified by OPF(Occasional Proportional Feedback) in accompany with the proper selection of controlling parameters. The periodic solution out of chaos can be easily archived by using one dimensional return map instead of two dimensional Poincare map suggested by OGY. The detailed technology of controlling chaos herein will be reported. |
