摘要：Magnetically shielded room (MSR) creates a zero-field environment for magnetoencephalography (MEG) research. Given the high cost of high-permeability materials and the low shielding factor at low frequencies, compensation coils combined with closed-loop control system are necessary for further dynamic shielding. To enhance the capacity of dynamic shielding, this paper proposes a dynamic field nulling method based on Smith predictor assisted generalized active disturbance rejection control (GADRC). Each component of the dynamic nulling system is analyzed and a high accuracy closed-loop system m
