Dynamics and Control of Nanopositioning Systems

Back
Abstract:
Nanotechnology is the science of understanding and control of matter at Dimensions of 100 nanometers or less. Encompassing nanoscale science, engineering and technology, nanotechnology involves imaging, measuring, modeling and manipulation of matter at this level of precision. An important aspect of research in nanotechnology involves precision control and manipulation of devices and materials at a nanoscale; i.e, nanopositioning. Nanopositioners are precision mechatronic systems designed to move objects over a small range with a resolution down to a fraction of an atomic diameter. The desired attributes of a nanopositioner are extremely high resolution and accuracy, stability and fast response. Conventional motion control technologies are unable to meet these requirements and provide the necessary precision. The key to successful nanopositioning is accurate position sensing and feedback control of the motion. In this talk we present an overview of nanopositioning technologies and devices, and we demonstrate how advanced control techniques can be employed to improve precision, accuracy and speed of operation of these systems.
