报告摘要：
Nanopositioning – the ability to accurately move matter at nanometer scales – underpins a wide range of science and technology domains including MEMS/NEMS, cell biology, stem cell research, micro / nanomanufacturing, sensor technologies etc. The dynamics of a typical nanopositioner are dominated by resonant mode/s and hysteresis. Additionally, issues such as creep and thermal drift further limit the positioning performance. Closed-loop control has long been investigated to overcome these detrimental issues. This talk will begin with a brief introduction of nanopositioning basics and move on to a crash course in the control of nanopositioning systems. Building upon this background, some recent developments in the control of nanopositioning systems will be presented. The talk will end with a list of avenues, yet unexplored – with a view to motivate the next generation of researchers to pursue these directions.
