## Abstract

A block switch controller for a linear motor is disclosed, the linear motor having a plurality of motor blocks, a shuttle which is propelled by the magnetic forces generated by a motor current passing through the motor blocks, a plurality of motor block switches selectively passing the motor current through the motor blocks, and a plurality of position sensors determining the position of the shuttle relative to the motor blocks, wherein the controller comprises a closed loop vector controller that incorporates a delay state having a feedback gain.
