Abstract
A method of controlling velocity of an armature of an electromagnetic actuator as the armature moves from a first position towards a second position is provided. The electromagnetic actuator includes a coil and a core at the second position. The coil generates a magnetic force to cause the armature to move towards and land at the second position. A control method is provided to ensure a near zero velocity landing of the armature in the second position while compensating for non-ideal external influences on the system.
