Multiloop Control of a Nanopositioning Mechanism for Ultraprecision Beam Steering

January 1, 2004
Author(s)
Jason J. Gorman, Nicholas Dagalakis, B G. Boone
Beam steering accuracy is critical to the successful operation of optical communications systems, especially those which take place over extreme length scales, such as for an interstellar spacecraft. In this paper, a novel beam steering mechanism and

Force Control of Linear Motor Stages for Microassembly
