Magnetic hysteresis in the force of a pre-biased E-core reluctance actuator is researched using three analysis methods. Simulations are performed with a 2d/3d finite element method (FEM) and two semi-analytic methods are evaluated namely, a generalization of the classical Preisach model (CPM), which is combined with a dynamic magnetic equivalent circuit (MEC) method, and a complex impedance model, which is combined with a static MEC model. Ultimately, the FEM simulations and analytic models are examined by a comparison to force measurements performed with a piezoelectric load cell.
