Optimal Data-Driven Difference-Inversion-Based Iterative Control: High-Speed Nanopositioning Tracking Example

open access: yesIEEE Transactions on Control Systems Technology, 2023
In this article, an optimal data-driven difference-inversion-based iterative control (ODDD-IIC) method is proposed for high-speed precision tracking in the presence of dynamics changes and random disturbances.

Adaptive control of a nanopositioning device [PDF]

open access: yes2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012
High-bandwidth tracking control is desirable in many nanopositioning applications, including scanning probe microscopy. Typical nanopositioner designs have several sources of uncertainty which can degrade control performance, and even induce instability.

On-Chip Cavity Optomechanical Coupling [PDF]

open access: yes, 2014
On-chip cavity optomechanics, in which strong co-localization of light and mechanical motion is engineered, relies on efficient coupling of light both into and out of the on-chip optical resonator.

Nanoscale-targeted patch-clamp recordings of functional presynaptic ion channels [PDF]

open access: yes, 2013
Important modulatory roles have been attributed to presynaptic NMDA receptors (NMDARs) located on cerebellar interneuron terminals. Evidence supporting a presynaptic location includes an increase in the frequency of mini events following the application ...

All-Optical Nanopositioning of High-Q Silica Microspheres [PDF]

open access: yes, 2017
A tunable, all-optical, coupling method has been realized for a high-\textit{Q} silica microsphere and an optical waveguide. By means of a novel optical nanopositioning method, induced thermal expansion of an asymmetric microsphere stem for laser powers ...
