Balancing the Inverted Pendulum: An Introduction to Fuzzy Logic Control

Control
With some practice, it’s possible to balance a broom upright in our hand, relying largely on intuition rather than calculation. Yet, the dynamics behind this seemingly…

2D Physics of the Inverted Pendulum on a Cart

Simulation
Control
When a broom balanced on your finger starts leaning right, you move your hand right to catch it. If you keep your hand still, gravity makes the lean grow until the broom…
