摘要
根据电路理论求得分数阶RL_α-C_β并联电路的导纳,以α=β、CR^2/L<<1为条件,求得RL_α-C_β并联电路相频特性的简易表达式,并对相频特性进行了理论分析和数值仿真分析,二者分析结果基本吻合,从而找到了相频特性随分数阶次数及元件参数变化的规律.
According to obtained in the condition of the theory of circuit, the admittance of the fractional order RLα-Cβ parallel circuit is α=β and CR2/L〈〈 1, a simple expression of the phase-frequency characteristic of the parallel resonant circuit is deduced, and the analysis and discussion are carried out. The theoretical analysis is in agreement with simulation result, and thus the law of phase-frequency characteristic with the change of element parameters and fractional order is found.
