Nanoscale control is the science of the control of objects at dimensions with 100 nm or less & the manipulation of them at this level of precision. The desired attributes of systems under nanoscale control design are extreme high resolution, accuracy, stability, & fast response. An important perspective of investigation in nanoscale control design includes system modeling & precision control devices & materials at a nanoscale dimension, i.e., design of nanopositioners. Nanopositioners are mechatronic systems with an ultraprecise resolution down to a fraction of an atomic diameter & developed to move objects over a small range in nanoscale dimension. After reviewing a lot of existing literatures for nanoscale control designs, the way to successful nanoscale control is accurate position sensing & feedback control of the motion. An overview of nanoscale identification, linear, & nonlinear control technologies, & devices that are playing a key role in improving precision, accuracy, & response of operation of these systems are introduced in this research.
