The observer is an unscented Kalman filter (UKF) for nonlinear systems that iteratively calculates an estimated mean and covariance of the state. It is based on a basic lumped parameter model, which contributes to the computational efficiency of the observer and facilitates its implementation. The magnetic reluctance is modeled taking into account the magnetic saturation and is partly defined by data obtained from finite element analysis (FEA). Boundary constraints are added to the estimated position to prevent it from surpassing its physical limits. Different tests performed with simulated and experimental data show that the estimations are accurate and robust to noise and model inaccuracies. Besides, although the observer has been developed for a specific device, the method can be easily extended to other electromechanical systems in which the position needs to be estimated. info:eu-repo/grantAgreement/ES/DGA/T04-FSE info:eu-repo/grantAgreement/ES/MEC/FPU14-04171 info:eu-repo/grantAgreement/ES/MINECO/RTC-2014-1847-6 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Sagues, Carlos Universidad de Zaragoza (orcid)0000-0002-3032-954X Ramirez-Laboreo, Edgar Universidad de Zaragoza (orcid)0000-0002-8977-5296 Llorente, Sergio (orcid)0000-0003-4609-1254 5007 520 Universidad de Zaragoza Dpto.
