The interaction of the lasers with the alkali metal atoms and inert atoms in the cell is used to maintain nucleon precessional motion in Larmor frequency, the magnetic field-driven technique is used to achieve closed-loop control of air chamber magnetic field, the resonance state of nucleon is kept by compensating the residual magnetism, and then the system angular rate can be sensed, which is the basic theory of nuclear magnetic resonance gyroscope (NMRG). Magnetic field drive technology, which is an important part of the closed-loop control of magnetic field, directly influences the precision and stability of NMRG. In order to solve the key technical problems of insufficient control accuracy and stability of NMRG magnetic field, a voltage-controlled current source of AC/DC separation design is studied to improve the control precision of the magnetic field. In addition, analysis and modeling of the field drive circuit noise based on noise analysis theory are carried out and the experiment is made for verification. The results show that the control precision of the transverse magnetic field of the 3-axis coil is ±0.046 2 nT and the control precision of longitudinal magnetic field is ±0.003 1 nT. The experiment proves that this technical solution has higher engineering application value.
