Closed-loop turbulence control is a critical enabler of aerodynamic drag reduction, lift
increase, mixing enhancement, and noise reduction. Current and future applications have …

Control can enable high-bandwidth nanopositioning needed to increase the operating
speed of scanning probe microscopes (SPMs). High-speed SPMs can substantially impact …

The problem of greenhouse gas (particularly carbon dioxide) release during power
generation in fixed and mobile systems is widely acknowledged. Fuel cells are …

Nanotechnology is the science of understanding matter and the control of matter at
dimensions of 100 nm or less. Encompassing nanoscale science, engineering, and …

In this article we analyzed and designed air flow controllers that protect the fuel cell (FC)
stack from oxygen starvation during step changes of current demand. The steady-state …

Fuel cell systems offer clean and efficient energy production and are currently under
intensive development by several manufacturers for both stationary and mobile applications …

Feedback and control theory are important ideas that should form part of the education of a
physicist but rarely do. This tutorial essay aims to give enough of the formal elements of …

In this brief, we study the design of a feedback and feedforward controller to compensate for
creep, hysteresis, and vibration effects in an experimental piezoactuator system. First, we …

This article describes an inversion-based feedforward approach to compensate for dynamic
and hysteresis effects in piezoactuators with application to AFM technology. To handle the …

Soft robots (SRs) represent one of the most significant recent evolutions in robotics.
Designed to embody safe and natural behaviors, they rely on compliant physical structures …
