Modeling of Magnetic Hysteresis.
Abstract
Magnetic hysteresis rods have been used successfully for damping the attitude motions of passively stabilized near-earth satellites. This paper describes the implementation of a model of magnetic hysteresis that is suitable for digital computer simulations of such motions. The model is based on the domain theory of magnetization, which assumes that a shifted rectangular hysteresis loop is associated with each domain. Coefficients used by the model are determined by least-squares fitting data from experimental hysteresis loops. For a type of hysteresis rod commonly in use, it is shown that a simplified version of the model may be used. Results from the theoretical model are compared with experimentally generated loops and show good agreement. (Author)
