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 ...

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

Mobile inverted pendulum (MIP) systems, typified by two-wheeled self-balancing robots and emerging wheel-legged platforms, present intrinsically unstable, underactuated dynamics that demand ...

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 ...
