Control apparatus and method of electromagnetic valve

摘要

A control apparatus of electromagnetic valve includes a valve body functioning as an intake valve or an exhaust valve of an internal combustion engine and an electromagnet for affecting an electromagnetic force relative to an armature provided on the valve body for actuating the valve body. A controler determines a target value regarding a force affecting the valve body when displacing the valve body from one displacement end to the other displacement end or a state quantity of the valve body varied in accordance with the force and controls the electromagnetic force of the electromagnet for attracting the armature to the one displacement side based on a deviation between the force or the state quantity and the target value so that the force or the state quantity conforms to the determined target value when displacing the valve body from the one displacement end to the other displacement end.
