AUTOMATIC MAGNETIC FIELD CONTROLLER FOR UNDERWATER OR SURFACE OBJECT Russian patent published in 2018 - IPC B63G9/06 

FIELD: electrical engineering.

SUBSTANCE: automatic magnetic field controller for underwater or surface object contains a signal receiving unit from the navigation complex, the Earth's magnetic field sensors or the object's magnetic field sensors, block of formation of the control algorithm for the automatic control system of the magnetic field of the object, control units for the field magnetic field compensators, compensators, control signal distribution unit, sensors of current harmonics, galvanic isolation unit, harmonic filters of currents of suppressed pulsations, blocks of adjustment of phases of currents, blocks of amplification and coordination of signals with parameters of a corresponding winding of demagnetization.

EFFECT: pulsations of the magnetic field of the object are reduced when the magnetic field is compensated for.
