Abstract
A method for controlling movement of an armature for an electromagnetic valve actuator. The armature moves between pole faces of juxtaposed solenoid coils. Voltage applied to armature capturing coil is varied in a closed-loop fashion as the armature moves through a flux initialization phase, followed by an armature landing phase whereby a soft landing of the armature is achieved during valve opening movement and valve closing movement.
