Ball and Beam
Introduce unstable closed loop system control concepts
The Ball and Beam module is ideal to introduce various control concepts related to unstable closed-loop systems. You can use it to demonstrate real-world control challenges such as aircraft roll control. The Ball and Beam module attaches to the Rotary Servo Base Unit.
Product Details
The Ball and Beam module consists of a steel rod in parallel with a nickel-chromium, wire-wound resistor forming the track on which the metal ball is free to roll. The track is effectively a potentiometer, outputting a voltage that’s proportional to the position of the ball.
When coupled to the Rotary Servo Base Unit, the tilt angle of the beam can be controlled by changing the servo gear angle. The Ball and Beam module can be operated in stand-alone mode, and the ball position can be controlled via the user interface.
