摘要：In magnetoencephalography (MEG) and cold atom clocks systems, measurement of target signals requires a near-zero magnetic environment. To achieve this, it is critical to apply external magnetic field to minimize the internal field. However, external magnetic compensation remains challenging due to the nonlinear relationship between the external magnetic field and remnant magnetism. Precise and parsimonious modeling for this nonlinear characteristic is important to enhance the magnetic compensation performance. Currently, two methods are employed for modeling the nonlinear behavior: analytical
