Researchers have demonstrated a way to maintain an unstable quantum system by applying bursts of microwave radiation. The technique is comparable to methods used for controlling an inverted pendulum ...

(a) The controller uses Parallel Distributed Compensator (PDC) as the control stratergy and Linear Matrix Inequality (LMI)-based stability conditions to achieve ...

Apparently, balancing a pole on top of a flying quadrocopter robot wasn't challenging enough for the researchers at ETH Zurich's Institute for Dynamic Systems and Control. Their latest project has two ...

A simple pendulum has two equilibrium points: hanging in the "down" position and perfectly inverted in the "up" position. While the "down" position is a stable equilibrium, the inverted position is ...
