摘要:
RLC并联电路是一种非常重要的单元电路，本文尝试着系统地分析和总结分数阶RLαCβ并联电路的基本特征和规律。对比整数阶RLC并联电路，电感的分数阶阶次α和电容的分数阶阶次β作为两个新的关键参数，使得分数阶RLαCβ并联电路在设计上有了更多自由度、更大的柔性和新意。同时，它们的引入也增加了许多新的现象和规律。本文首先分析了分数阶RLαCβ并联电路的两个基本特性：导纳和相位。进而分析了分数阶条件下分数阶RLαCβ并联电路所特有的纯虚阻抗的问题。并且，分析了LC电路中特有的现象之一--谐振，和五个参数对谐振的影响。进一步地，阻抗和相位关于各参数的敏感性分析也得到了详细地研究。数值分析和理论分析两者互相印证，彼此支持。
Abstract:
Since the RLC circuit is a basic circuit, attention is directed to the generalization of the fundamentals of fractional multiple RLαCβ circuit. Compared with the conventional multiple RLC circuit, the effects of fractional orders, αand β, is the key factor for extra freedom, more flexibility and novelty. First, we study the basic features including the admittance and phase. Then, the conditions for fractional-order multiple RLαCβ circuit to act as pure imaginary impedances are derived, which are unrealizable in the conventional case. As a peculiar phenomenon-resonance, the relationships among resonance frequency, fractional order and LC are studied in detail. In addition, sensitivity analysis including some interesting rules is illustrated. Finally, numerical simulations are carried out to validate the above studies.
