Controlling motion of armature of electromagnetic actuator for gas exchange valve of combustion engine |
摘要 |
The armature is moved in an oscillating manner between two electromagnet coils, against the force of respective restoring springs. A control unit detects if the armature is currently at the yoke of an electromagnet coil by determining if the armature position lies between maximum and minimum positions. A mathematical model is used to estimate the velocity of the armature.
