Admittance and impedance controllers are often purely feedforward, using measured external force or motion, respectively, to generate a reference for an inner-loop controller. In this case, the range ...

Metaphors are shaped by experience and also contribute to shaping it. Common idioms attempt to capture the dynamics of the ...

What can the systems theory distinction between positive and negative feedback tell us about how recovery succeeds?

Creating a culture where feedback flows openly and constructively is essential to employee growth and organizational health. But giving and receiving feedback in a way that’s both timely and helpful, ...

The excitement is shocking because most of us hate to get negative feedback. I certainly dislike it, and most often respond defensively. When I can remind myself, this simple principle helps me ...

The optical negative-feedback laser monolithically integrated on an InP substrate for obtaining narrow linewidth is investigated. Optical negative feedback (ONF) induced by reflection of light from a ...

In football, defense keeps the opposing team in check. A similar strategy is at play inside our cells. Negative feedback loops (NFLs) help regulate how cells respond to signals, for example ...

The global shift towards a clean-energy system is much more than just a technological switch – it is a profound transformation of markets, industries and societal behaviours. This complex undertaking ...

Badmouthing a higher-up publicly won't make sense for most people. But there are other, more practical ways to deliver feedback to a superior.
