Title: | Design of normalized fractional adaptive algorithms for parameter estimation of control autoregressive autoregressive systems | Authors: | Chaudhary N. Ahmed M. Khan Z. Zubair S. Raja M. Dedović, Nebojša |
Issue Date: | 1-Mar-2018 | Journal: | Applied Mathematical Modelling | Abstract: | © 2017 Elsevier Inc. In this paper, strength of fractional adaptive signal processing is exploited for parameter identification of control autoregressive autoregressive (CARAR) systems using normalized version of fractional least mean square (FLMS) and its recently introduced modification of type 1 and 2. The adaptation performance of the proposed normalized FLMS methods is compared with standard counterparts for CARAR identification model by taking different noise levels as well as fractional orders. The results of the statistical analyses are used to validate the consistency of the proposed normalized fractional adaptive methodologies in terms of convergence, accuracy and robustness. The reliability and effectiveness of the design schemes is further validated through consistently approaching the desired identification parameters based on performance metrics of mean square error, variance account for and Nash–Sutcliffe efficiency. | URI: | https://open.uns.ac.rs/handle/123456789/1758 | ISSN: | 0307904X | DOI: | 10.1016/j.apm.2017.11.023 |
