The inverted pendulum is a classic problem in dynamics and control theory and is widely used as a benchmark for testing control algorithms (PID controllers, state-space representation, neural networks, fuzzy control, genetic algorithms, etc.). Variations on this problem include multiple links, allowing the motion of the cart to be commanded ...
A double inverted pendulum is the combination of the inverted pendulum and the double pendulum. The double inverted pendulum is unstable, meaning that it will fall down unless it is controlled in some way. The two main methods of controlling a double inverted pendulum are moving the base, as with the inverted pendulum, or by applying a torque ...
Rotational Inverted Pendulum: Classic pedagogical example of application of control theory. The Furuta pendulum, or rotational inverted pendulum, consists of a driven arm which rotates in the horizontal plane and a pendulum attached to that arm which is free to rotate in the vertical plane.
A Carathéodory-π solution can be applied towards the practical stabilization of a control system. [6] [7] It has been used to stabilize an inverted pendulum, [6] control and optimize the motion of robots, [7] [8] slew and control the NPSAT1 spacecraft [3] and produce guidance commands for low-thrust space missions.

In 1987, Takeshi Yamakawa demonstrated the use of fuzzy control, through a set of simple dedicated fuzzy logic chips, in an "inverted pendulum" experiment. This is a classic control problem, in which a vehicle tries to keep a pole mounted on its top by a hinge upright by moving back and forth.
The classic inverted pendulum is an example of a trivially underactuated system: it has two degrees of freedom (one for its support's motion in the horizontal plane, and one for the angular motion of the pendulum), but only one of them (the cart position) is actuated, and the other is only indirectly controlled. Although naturally extremely ...
The inverted pendulum is stabilized by constant feedback from the brain and can operate even in the presence of sensory loss.In animals who have lost all sensory input to the moving limb, the variables produced by gait (center of mass acceleration, velocity of animal, and position of the animal) remain constant between both groups.
Cart-pendulum. The control theory is using differential equations to describe complex physical systems like an inverted pendulum. [1] A set of differential equations forms a physics engine which maps the control input to the state space of the system. The forward model is able to simulate the given domain.
