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 (SRV02). Using this experiment, students learn to:
In addition to teaching intermediate control concepts, the Ball and Beam can be used for research in various areas, including neural networks and nonlinear control.
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. The Ball and Beam module can also be paired with an additional Remote Sensor module, in which case the system operates in a Master/Slave mode where the ball on the beam will follow the reference ball position of the second Ball and Beam module.
The Ball and Beam module comes with Quanser-developed courseware standardized for ABET evaluation criteria. The workbook with exercises, together with the quick setup resources, a comprehensive User Guide, pre-designed controllers and the system model allow you to get your lab running faster, saving months of time typically required to develop lab materials.
Topics Included in Quanser-developed Courseware:
To set up your Ball and Beam workstation, you need additional components. Quanser engineers recommend:
¹ alternatively, you can use Q8-USB, QPIDe or any equivalent NI DAQ device supported by QUARC
² NI cRIO-9074, or NI cRIO-9024 with cRIO-9113 chassis
³ NI DAQ device must be supported by Quanser RCP toolkit. Alternatively, you can use Quanser Q2-USB, Q8-USB, or QPIDe
