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 ...

New research enables powered prosthetics to dynamically respond to the wearer’s environment and help amputees walk. Wearers of the robotic leg could walk on a treadmill almost as fast as an ...

The goal of controlling a system is to reach or retain stability. In control theory, stability is described with the Lyapunov stability criteria and mathematical models that set into relation the ...

In the last 150 years, engineers have developed and mastered ways to stabilize dynamic systems, without lag or overshoot, using what's known as control theory. Now, a team of University of Arizona ...
