摘要：
A promising method for enhancing automotive internal combustion engine efficiency uses solenoid actuators to directly control gas exchange valves. Mitigation of valve seating velocities is challenging due to phenomena such as magnetic saturation and pressure disturbances. Production implementation of an electromagnetic valvetrain will require the development of cost effective yet accurate sensors for robust feedback control. A method of magnetic flux-based armature position measurement is presented. An overview of the modeling and control design is shown with experimental and simulated results using such a sensor configuration.
