ELECTROMAGNETIC TRACKING DRIVE Russian patent published in 2006 - IPC H02P25/06 H01F7/18 

FIELD: electric automatics.

SUBSTANCE: drive is realized on basis of subordinated coordinates adjustment principle with linear position adjuster, subordinated to current adjustment contour additional nonlinear current check connection, which has transfer coefficient, proportional to coil inductance values G(z), where z - coordinate of core position, and operates at input of dividable division block 4. due to nonlinear control algorithm, linearization of natural nonlinear properties of electromagnetic engine is performed and, thus, high characteristic of adjustment quality are provided for in whole range of core position change.

EFFECT: increased quality of core position adjustment in tracking system with electromagnetic engine.
