Magnetic force based actuator control
Abstract:
An electromagnetic actuation system includes an actuator having an electrical coil, a magnetic core, and an armature. The system further includes a controllable drive circuit for selectively driving current through the electrical coil. A control module provides an actuator command to the drive circuit effective to drive current through the electrical coil to actuate the armature. The control module includes a magnetic force control module configured to adapt the actuator command to converge magnetic force within the actuator to a preferred force level.
