摘　　要：消磁电流控制技术是舰船消磁系统的关键技术,根据XC-4DJ型消磁电流控制仪的硬件电路,提出了一种可以适用于舰船在任何纬度区、任意状态下的地磁三分量真值计算及消磁电流控制模型,并给出一种干扰量测量和计算的方法,提高磁强计式数控消磁系统的电流控制精度,为切实提高舰船的磁性防护能力提供了一种新途径。The current control technology is the key of the ship degaussing system. According to the hardware circuit of XC-4DJ degaussing system current controller,a geomagnetic field components calculation and degaussing current control model was proposed, which can be used for the ship with general situation in random latitude. In addition, one method of measurement and calculation for the interference magnetic fields was founded. The model and the method improved the current control precision of the magnetometer numerical control degaussing system,which supported a novel approach for improving the magnetic defense ability of the ship.
