Abstract:
Aspects of the invention provide methods and systems for moving moveable stages relative to a stator. A stator is operationally divided into multiple stator tiles. The movement of the one or more moveable stages is controlled by a plurality of controllers (each assigned particular control responsibilities). A controller is provided for each stator sector, where each stator sector comprises a group of one or more stator tiles. Controllers from neighboring sectors share various information to facilitate controllable movement of one or more moveable stages relative to the stator.
