Iterative Learning Control for Precision Motion Control of Microscale and Nanoscale Tracking Systems
… techniques are used to custom-design the ILC for precision tracking of aggressive trajectories suitable for rapid microscale and nanoscale manufacturing, assembly, or scanning. They are also useful for applications where disturbance signals may change rapidly such as in micro- and nano-materials …

System Identification of a Cantilever Beam with Interferometer Measurement Using Adaptive Filters
<p>Laser interferometry, commonly used in high-precision motion control systems, is rarely adopted in experimental vibration analysis because its installation and mounting is invasive to dynamical systems. However, metrology systems that already utilize laser interferometry, such as profilometry in …

Accurate capacitive metrology for atomic force microscopy
… microscope (AFM) originally developed in the MIT Precision Motion Control Lab. The capacitive measurements use a set of commercial capacitance sensors intended primarily for use against a flat target. In our design, the capacitance sensors are used with a spherical target in order to be …

Precision coordination and motion control of multiple systems via iterative learning control
… of multiple systems. Traditional approaches for controlling these systems often neglect the underlying coupling in the application. To stay at the forefront of these fields requires the development of innovative approaches to new challenges. The research in this dissertation focuses on designing …

Vision based iterative learning control for a roll to roll micro/nano-manufacturing system
… the presence of hybrid stepping/scanning motions, both continuous and start/stop motions, should be performed with similar levels of precision. Since the web undergoes a repetitive trajectory, Iterative Learning Control (ILC) can thereby be used to improve the position tracking precision, …
