Abstract:The three-axis active magnetic compensation system suppresses magnetic field disturbances around a magnetically shielded room for ultra-weak magnetic field measurements. However, coupling among control axes increases the complexity of disturbance suppression. To address this issue, a discrete control method is proposed. A decoupling matrix is designed to transform the system into three independent single-input singleoutput subsystems. For each subsystem, a discrete extended state observer is employed to estimate residual coupling and environmental disturbances online, and a discrete integral s
