Method for estimating the position and the velocity of an EMVA armature

摘要

A method is disclosed and claimed for estimating the position and the velocity of a valve armature in an electromagnetic valve actuation system, which includes a first solenoid coil that energizes and attracts the valve armature based on a first solenoid command. The method includes obtaining a parameter for the first solenoid command, measuring a property of the first solenoid coil, and estimating the position and the velocity of the valve armature based on the obtained parameter and the measured property.
