Known analytical models lead to trans-cendental system descriptions with fractional-order characteristics, not suited for the actuator control. Although analytical approximations resolve the issue, the inclusion of minor perturbations leads to impractical model orders, which require simplifications and compromise the model accuracy. This article studies numerical methods to directly approximate the transcendental systems or measurement data, allowing for a high accuracy with sufficiently low orders. We improve existing approaches like Levy\u2019s method and vector fitting and apply them to a fractional-order system. Using measurement data, a comparison shows that the numerical approaches match or excel our previously studied analytical approximations.<\/jats:p>","DOI":"10.1515\/auto-2022-0002","type":"journal-article","created":{"date-parts":[[2023,3,10]],"date-time":"2023-03-10T00:52:41Z","timestamp":1678409561000},"page":"186-197","source":"Crossref","is-referenced-by-count":0,"title":["Selected numerical methods to model the fractional-order system behavior of nonlaminated magnetic actuators"],"prefix":"10.1515","volume":"71","author":[{"given":"Robert","family":"Seifert","sequence":"first","affiliation":[{"name":"Faculty of Electrical and Computer Engineering, Chair of Electrical Machines and Drives , Technische Universit\u00e4t Dresden , Helmholtzstr. 9, D-01069 Dresden , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Hecht","sequence":"additional","affiliation":[{"name":"Department of Information Technology and Electrical Engineering , ETH Z\u00fcrich , Gloriastrasse 35, CH-8092 Z\u00fcrich , Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wilfried","family":"Hofmann","sequence":"additional","affiliation":[{"name":"Faculty of Electrical and Computer Engineering, Chair of Electrical Machines and Drives , Technische Universit\u00e4t Dresden , Helmholtzstr. 9, D-01069 Dresden , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2023,3,10]]},"reference":[{"key":"2023033111483239957_j_auto-2022-0002_ref_001","doi-asserted-by":"crossref","unstructured":"J.
