摘要

The results of the classical analysis of transient states in the circuit with supercapacitor don't match the results of the experiments. For more accurate description of the real circuit properties the fractional orders calculus for modeling of such circuits are taken. For Cole-Cole model the transfer function of supercapacitor is derived. The approximation of the transfer function frequency characteristics is based on minimization of the performance index. The performance index is a sum of square values of relative approximation errors for measured points of the frequency characteristics presented in the literature. The MA TLAB fmin-search function based on Nelder-Mead simplex optimization method is applied.
