The Ball & Beam control system is a classic control teaching aid especially designed for courses in automatic control principle, modern control engineering, and electrical motor control — with operating characteristics typical of inherently unstable systems, as found in aircraft, ships and robots for example.
The Ball & Beam control system designed by Googoltech is able to control the position of a stainless steel ball on the track by adjusting the rotating angle of a beam. It consists of a v-grooved steel bar and a free rolling ball. The linear sensor measures the position of the ball on the track by measuring the output voltage from the stainless steel bar. A DC motor is connects to a gear reducer, which controls the angle of beam, accordingly realize the position control of the ball.
A dynamic and visually-motivating system, the Ball & Beam control system gives an impressive insight into the power of control theory.
