Title: | A Low-Complexity Method for Parameter Estimation of the Simplified Randles Circuit with Experimental Verification | Authors: | Mitar Simić Adrian Stavrakis Goran Stojanović |
Keywords: | Electrical impedance spectroscopy, Randles circuit, parameter estimation, microcontroller-based platforms | Issue Date: | 1-Nov-2021 | Project: | H2020 STRENTEX | Journal: | IEEE Sensors Journal | Abstract: | In this paper we present a processing-efficient method for parameter estimation of a Randles circuit. As our approach is not iterative, it does not require for an initial guess of model parameters to be provided. The low-complexity of the provided set of closed-form expressions enables the implementation on microcontroller-based platforms. The presented approach is verified with simulations (using both noiseless data and data with noise) and with experimentally obtained data (Randles circuit made from discrete components; impedance of microfluidic platform for isomalt detection; impedance of Panasonic 18650PF Li-ion Battery). Additionally, it was implemented on a microcontroller board based on ATmega2560 microcontroller with available 256 kB of flash memory, 8 kB of SRAM and clock speed of 16 MHz. Reliable and accurate estimations of such implementations confirmed the suitability of this work for low-cost embedded hardware | URI: | https://open.uns.ac.rs/handle/123456789/32438 | ISSN: | 1558-1748 | DOI: | 10.1109/JSEN.2021.3110296 | Rights: | Attribution-NonCommercial-ShareAlike 3.0 United States |
