Universidad de Zaragoza (orcid)0000-0002-8977-5296 Reluctance actuator characterization via FEM simulations and experimental tests 2018 Access copy available to the general public Unrestricted Modeling the reluctance of an electromagnetic actuator is a critical step to analyze its dynamics and design model-based controllers. On the one hand, analytical expressions based on either theoretical or empirical models often lack accuracy due to model inconsistencies. On the other, numerical methods are much more precise but require exact information about the system geometry, materials and winding configuration. In this paper we present a new method that brings together the good properties of the finite element method and of system identification techniques to obtain an accurate description of the reluctance and its derivative. Since the method is designed to identify the unknown parameters of the system, it is particularly well suited for modeling existing commercial devices. An application on a safety valve used in gas lines is included to illustrate the method and a discussion on the results shows the advantages of our proposal. info:eu-repo/grantAgreement/ES/MEC/FPU14-04171 info:eu-repo/grantAgreement/ES/MINECO/RTC-2014-1847-6 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.978 2018 ENGINEERING, MECHANICAL 30 / 129 = 0.233 2018 Q1 T1 ENGINEERING, ELECTRICAL & ELECTRONIC 96 / 265 = 0.362 2018 Q2 T2 AUTOMATION & CONTROL SYSTEMS 24 / 62 = 0.387 2018 Q2 T2 COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE 43 / 132 = 0.326 2018 Q2 T1 0.848 2018 Electrical and Electronic Engineering 2018 Q1 Mechanical Engineering 2018 Q1 Computer Science Applications 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/submittedVersion Sagues, C.
