摘要：The high-precision measurement for the cardiac magnetic field signal is highly sensitive to magnetic fluctuations within a magnetic shielding device. The active magnetic compensation (AMC) is an effective method for suppressing these disturbances. Due to the measurement delay of the feedback sensor, the suppression of magnetic field fluctuations is insufficient. A high-precision magnetic field disturbance suppression method based on delay and interference compensation is proposed in this paper. This method employs a time delay compensation system based on the Smith predictor (SP) to address th
