摘要本文提出了一种基于分数阶模型的识别方法，其目标是确定电池单元的老化。该方法避免了分数阶算子的集总近似。此外，通过这种方法，可以识别物理激励的电池单元参数。其基本思想是将测量值的导数转换为所谓的调制函数。借助仿真的一个强大的行为对测量噪声。可以使用该方法进行在线电池识别。
Abstract This paper considers a fractional modelbased identification method with the objective to determine the aging of a battery cell. The method avoids lumped approximations of the fractional operator. Moreover with this approach it is possible to identify physically motivated battery cell parameters. The basic idea is to transfer the derivatives from the measurements to the so called modulating functions. With the help of simulations a robust behavior against measurement noise is shown. It is possible to use the method for online battery identification.
