摘要：The three-axis active magnetic compensation (TAMC) system is widely used to suppress environmental magnetic disturbances in magnetically shielded room (MSR), enabling stable ultra-weak magnetic measurements with reduced cost. Nonlinear, time-varying, and coupled behaviors induced by the shielding material’s magnetic properties pose challenges to accurate modeling and disturbance suppression. A composite control strategy combining linear extended state observer (LESO) with integral sliding mode control (ISMC) is proposed. The LESO is implemented for each axis to provide real-time estimates of e
