Inverted pendulum
Also called cart and pole, an inverted pendulum is a pole attached to a moving cart. Whereas a normal pendulum heads down, an inverted pendulum is an actively balanced "standing" pole. The movement of the cart has to be controlled to keep the pole upstraight.The inverted pendulum is a widely used benchmark for testing control algorithms ( PID controller, neural networks, ...). Modern controllers are capable of even balancing multiple linked pendulums.
