Abstract :
This article is based on enhanced incremental energy method to derive the inductance model of sensorless position detection in solenoid valve. Determine solenoid valve operating area according to the B-H curve of the magnetic material and through the incremental energy can obtain the static and dynamic inductance model of solenoid valve. The inductance model is confirmed to be right by compared with the result of the finite element. Based on the dynamic inductance model, this paper realized the sensorless position detection in solenoid valve.
