Abstract
A system for effecting the adjustment of the armature of a solenoid into a desired position as indicated by an input analog signal representation of desired armature position. When the actual position of the solenoid armature does not correspond to the desired position in a first or in a second relationship, respective mutually exclusive first and second proportional and respective corresponding mutually exclusive first and second integral error signals are produced. The corresponding proportional and integral error signals are summed and circuitry responsive to the sum of these signals effects the adjustment of the solenoid armature into the desired armature position.
