"In this work, we have demonstrated that we can control the quantum dynamics of a cloud of atoms to maintain them in a non-equilibrium configuration analogous to the inverted pendulum," said ...

A classic problem in this area is the inverted ... pendulum is attached at one point to the cart. By moving the cart back and forth, the pendulum can be kept in a vertical position. The control ...

Stabilizing an inverted pendulum is a classic problem in control theory ... seeing pages full of differential equations and bode diagrams just to describe its basic operation.
