Ball Balancing Table

Balancing a ball on a table in a desired position is one of the most important and classical problems of control theory. Altair, partnering with ACROME, promotes the unique experience of a digital twin mechatronics simulation and hands-on experiment platform to teach and learn model-based controller design concepts with a 3D+lD system co-simulation engine.

The Ball Balancing Table (BBT) is a well-known kit for all mechatronics enthusiasts. Even if it might appear quite simple, it allows to investigate many aspects of control, for example anti-windup scheme for PID control.

The main parts of the BBT kit are:
     
 
  • Power Supply
  • Controller (Arduino)
  • RC Servos
  • 2D resistive touch screen
  • Steel Ball
 
     
The position of the ball, measured by the touchscreen, is fed as input to the controller, which comparing it with the reference produces an error signal. This error signal is converted accordingly to a certain control logic into a command which drives the RC servos. The movement of the servos is transmitted to the table through rod end bearings, allowing the ball to follow the set reference.
     
   
     
 
FEATURES

Altair Activate

 
Altair Activate� software is an open & flexible tool for rapidly modeling and simulating products as multi-disciplinary systems in the form of 1D models (expressed as signal-based or physical block diagrams), optionally coupled to 3D models. Recently, it can also run hardware in the loop simulations, making it a perfect platform to develop mechatronic systems, such as:

The following is the typical workflow for a typical BBT experiment
     
   
     
The closed loop system can be easily modeled in Altair Activate through this block diagram:
     
   
     
The last step is to test and validate the controller with the real BBT kit. This means that we are performing a hardware in the loop simulation.

As you can see the digital twin and the real BBT kit behave almost the same:
