In the second chapter, we discuss some properties of chaos in a rf - current biased josephson junction with linear and quadratic damping respectively
第二章討論了線性阻尼和平方阻尼下的josephson結中的混沌問題。 -
It is shown that vibration suppression efficiency of these kind of treatments depend much more on the viscoelastic layer thickness, material properties and the piezoelectric layer thickness. secondly, a linear quadratic regulator and output feedback are used to actively control vibration. it is shown that placing the active element on the opposite side of pcld or underneath pcld is capable of vibration suppression with lower control effort and more inherent damping
定義了主被動混合阻尼結構控制性能指標：被動抑振性能指標、主動抑振性能指標、控制能量指標和控制力性能指標；然後，基於狀態反饋最優控制律，根據定義的控制性能指標分析粘彈性阻尼層厚度、粘彈性阻尼材料參數、壓電作動層厚度對主被動混合阻尼結構振動控制性能的影響，得到了一些有價值的結論。 -
As for the latter, based on linear quadratic regulator theory and linear quadratic gaussion theory, discussion is carried about parameter optimum of ved whose mechanical model is an equivalent stiffness and equivalent damping one. according to linear quadratic regulator theory matrix elementary transform and least - squares method, formulas about parameter optimum of ved are achieved
在粘彈性阻尼器參數優化方面，採用等效剛度和等效阻尼為力學模型，基於線性二次型高斯（ lqg ）最優控制問題和線性二次型（ lqr ）最優控制問題的理論對ved的參數優化進行了討論。
