摘要：Abstract Magnetically shielded rooms (MSR) composed of high-permeability materials provided a near-zero magnetic environment for ultra-weak field measurements, such as biomagnetic cardiography and encephalography. To maximise material performance, a demagnetization current is applied to increase the effective permeability, thereby enhancing the shielding performance of the MSR. However, conventional open-loop demagnetization system is susceptible to disturbances that distort the current waveform and degrade the demagnetization effect. To improve disturbance suppression, this paper proposes a c
