A Technique for Parameter Eestimation of Equivalent-Circuit Models

Abstract

The paper describes a simple algorithm for parameter estimation of equivalent-circuit models on the basis of comparison calculated and measured electrical impedance. The algorithm searches in multidimensional space in the vincinity of expected results. Despite the simple calculations, the algorithm easily outstrip number of high-order mathematical and algorithmic methods, such as non-linear least squares, neural networks etc. The algorithm is easily realizable and outputs are highly accurate in comparison to experimental data.
