    摘要: A system includes a plurality of actuators configured to provide forces to an actuatable member to actuate the member between a first position and a second position during an actuation mode. The actuators are also configured to return the member from the second position to the first position during a retrace mode. The system also includes a controller configured to control the actuators. The controller is configured to identify a back electromotive force (BEMF) of each of the actuators during the retrace mode. The controller is also configured to responsively provide control signals to drive the actuators such that the forces provided by the actuators to the member during the actuation mode are substantially equal.
