<P>PROBLEM TO BE SOLVED: To provide a linear actuator control apparatus capable of relieving, in a simple structure, the impact which a movable part such as a plunger exerts on a portion where the movable part is in contact with at its initial state, when an electromagnetically controlled linear actuator drastically resumes the initial state. <P>SOLUTION: A linear actuator control apparatus defines a correction current Ic as a target current It; and controls a drive current based on the target current It, when the target value Is of the drive current is equal to or less than a reference current Ia, where the correction current Ic is a value configured according to the drive current when driving force and pressing force become in balance at a position where an end of a plunger comes in contact with a contact member, and the reference current Ia is a value configured as a value equal to or less than the correction current Ic. <P>COPYRIGHT: (C)2012,JPO&INPIT |
