ABSTRACT:
A dual magnet controller, as part of an active roller guide (ARG) controller, that requires that each controlled actuator produce at least a minimum idling force, rather than carrying a minimum idling current. The dual magnet controller for a particular control axis determines force commands for its pair of actuators based on the actuators in combination having to produce a net force, and each actuator independently having to produce a force equal in magnitude at least to a pre-determined minimum idling force. The net force may be calculated by other elements of the ARG controller and communicated as input to the dual magnet controller.
