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 ...

At the Houston Museum of Natural Science they recently made a disturbing discovery: their Foucault pendulum had stopped ...

The Takagi--Sugeno (T--S) fuzzy descriptor system offers a promising avenue for controlling non-linear systems but lacks optimal control strategies. Moreover, while robust control methods have been ...

Reaction wheels are useful things, typically used by satellites to keep themselves oriented the right way up in space. Turning the reaction wheel creates an equal and opposite torque in the spacecraft ...

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