Abstract: An electromagnetic actuation system includes an electrical coil, a magnetic core, an armature, a controllable bi-directional drive circuit for selectively driving current through the coil in either of two directions, and a control module providing an actuator command to the drive circuit. Current is driven though the electrical coil in a first direction when an actuation is desired. When the actuation is not desired current is driven through the electrical coil including in a second direction sufficient to reduce residual flux within the actuator below a level passively attained within the actuator at zero coil current.
