Negative Imaginary (NI) systems theory is an emerging branch of control theory that focuses on the frequency response characteristics of dynamical systems. At its core, the theory exploits conditions ...

Control theory is the study of how one can use feedback to modify the behavior of a system — such as a robot, vehicle, chemical or biological process, power grid, stock portfolio, or an ecosystem — so ...

The well-known and nearly hundred years old "proportional-integral- derivative"(PID) controller is a linear feedback control method which adjusts the input signal by ...

Engineering principles developed only 150 years ago were found to have evolved first in biological circuitry that controls cell growth, according to new research. In the last 150 years, engineers have ...

It seems as though we still can’t hit the ceiling on better control schemes for 3D Printers. Input Shaping is the latest technique to land on our radar, a form of resonance compensation that all but ...

When I was an undergrad I took a course on feminism that was interesting and challenging, but one of the things I remember most from it was only peripherally related to feminism per se. In one part of ...
