ABSTRACT:
A control apparatus for an electromagnetically driven valve is provided which is applied to an electromagnetically driven valve in which a movable portion including an armature and a valve element is driven using an electromagnetic force generated by an electromagnet. This control apparatus includes a controller. This controller performs feedback control such that a value of a current which is actually supplied to the electromagnet becomes substantially equal to a value of a desired attracting current when displacing the movable portion by supplying an attracting current to the electromagnet. Further, the controller variably sets a feedback gain used in feedback control of the attracting current, based on a distance between the electromagnet and the armature.
