摘要

本文的目的是研究使用含有分数级电容器的科尔阻抗模型模拟心脏细胞膜电学特性的可能性。提出了一种基于电压阶跃作用下的电流瞬态响应来确定模型参数的方法。该方法基于MATLAB函数fminsearch对模型记录的瞬态响应与计算的瞬态响应之间的最小二乘误差进行数值最小化。在膜模型中使用分数阶电容器与传统电容器相比，可以减少建模误差。

Extraction of Cardiac Cell Membrane Fractional-Order Capacitance from Current Response to Voltage Step

The aim of the article is to examine the possibilities of modeling electrical properties of cardiac cell membrane using the Cole impedance model containing a fractional-order capacitor. A method is presented to determine the parameters of the model based on the current transient response to a voltage step applied to the membrane. The method is based on the numerical minimization of the least squares error between the recorded and calculated transient response of the model using the MATLAB function fminsearch. The use of a fractional-order capacitor in the membrane model is found to result in a reduction in the modeling error compared to that of the classic capacitor.
