Electromagnetic actuator controller for intake/exhaust valve, applies brake to armature based on load condition of armature, in response to release of armature held in one of end positions

摘要

An actuator (100) has a pair of electromagnets (11,13) which drive an armature between two end positions. A controller (1) applies brake to the armature in accordance with a load condition of the armature, in response to a release of the armature held in one of the end positions. Independent claims are included for the following: (1) Electromagnetic actuator control program; and (2) Electromagnetic actuator control method.
