Nanopositioning for Polarimetric Characterization

Journal of Nanoscience and Nanotechnology, 2008
A positioning system with approximately nanometer resolution has been developed based on a new implementation of a motor-driven screw scheme. In contrast to conventional positioning systems based on piezoelectric elements, this system shows remarkably low levels of drift and vibration, and eliminates the need for position feedback during typical data ...

Impulsive control for fast nanopositioning

Nanotechnology, 2011
In this paper we present a non-linear control scheme for high-speed nanopositioning based on impulsive control. Unlike in the case of a linear feedback controller, the controller states are altered in a discontinuous manner at specific instances in time.

Nanomeasuring and nanopositioning engineering

SPIE Proceedings, 2006
Abstract The paper describes traceable nanometrology based on a nanopositioning machine with integrated nanoprobes. The operation of a high-precision long range three-dimensional nanopositioning and nanomeasuring machine (NPM-Machine) having a resolution of 0.1 nm over the positioning and measuring range of 25 mm × 25 mm × 5 mm is explained.

Nanopositioning for storage applications

Annual Reviews in Control, 2011
Abstract In nanotechnology applications, nanopositioning, i.e., nanometer-scale precision control at dimensions of less than 100 nm, plays a central role. One can view nanopositioners as precision mechatronics systems aiming at moving objects over a certain distance with a resolution that could be as low as a fraction of an Angstrom.

Impulsive control for nanopositioning

Proceedings of the 14th international conference on Hybrid systems: computation and control, 2011
In this paper, impulsive control is applied to a class of linear feedback systems and studied both theoretically and experimentally, with a particular focus on the usage in nanopositioning. By using impulsive control, improvements in tracking performance and tolerance to measurement noise can be achieved which are beyond the limits of conventional ...
