摘要: Abstract Modeling the reluctance of an electromagnetic actuator is a critical step to analyze its dynamics and design model-based controllers. On one hand, analytical expressions based on either theoretical or empirical models often lack accuracy due model inconsistencies. other, numerical methods are much more precise but require exact information about system geometry, materials winding configuration. In this paper we present new method that brings together good properties finite element identification techniques obtain accurate description derivative. Since designed identify unknown parameters system, it particularly well suited for modeling existing commercial devices. An application safety valve used in gas lines included illustrate discussion results shows advantages our proposal.
