Ball and Beam:

This system is composed of a beam attached to a motor, and a ball placed on the beam.
The ball is allowed to roll with one degree of freedom along the length of the beam. The control goal is to place the ball at certain desired position, by changing the beam angle.This kind of system type is often encountered in control applications. This unstable system is a good example for learning how control techniques can be applied to stabilize a plant.
Two different control strategies have been implemented: manual control and PID control.
