Ball and Beam Infosheet
Ball and Beam Infosheet
The Ball and Beam system is a versatile tool for control system design, ranging from basic linear controllers to advanced nonlinear methods. It provides a hands-on approach for students to understand system design, allowing them to visually analyze the effects of linearization, modeling errors, and control algorithm deficiencies through a Graphical User Interface (GUI) that displays simulated responses and real measured values.
The system is available in NI LabVIEW or Matlab/Simulink as open-source software, enabling students to implement their own controller designs. It includes a predesigned ball-and-beam model and controllers for performance measurement and response observation. The GUI features a 3D model of the system, facilitating the analysis of steady-state errors, phase differences, and amplitude ratios for both simulated and real systems.
This system allows students to apply control theory by controlling the position of a ball on a beam, a classic problem in control theory. It bridges the gap between real industrial systems and DIY approaches, with compatibility for NI myRIO and Arduino, enabling quicker and easier design of complex applications.

BALL AND BEAM Realize control theory with ACROME Ball and Beam System! Controlling the position of a ball on a beam is one of the conventional problems of the control theory. OVERVIEW Ball and Beam system can be used for a wide range of control system design implementations from basic linear controllers to advance nonlinear methods. Students are able to understand system design approaches with hands-on methodology. Effects of linearization, modelling errors and control algorithm's defficiencies could be visually distinguished and further analyzed thanks to the provided Graphical User Interface. User Interface contains plots of the simulated response and system's real measured values. OPEN-SOURCE EMBEDDED SOFTWARE Ball and Beam System, with its easily accessible and student-friendly components, is a hands on experiment, closing the gap between real industrial systems and DIY-approach. Compatibility of NI myRIO and Arduino enables the students to design complex applications and engineering systems quicker and easier than ever before. CREATIVE USER-FRIENDLY GUI Available in NI LabVIEW or Matlab / Simulink as an open source software allows students to implement their own controller designs. Predesigned ball-and-beam model and controllers are ready for performance measurements and observing responses of fundamental controller types. User-friendly GUI includes 3D model of ball-and-beam system. Steady-state error for standard test inputs, phase difference and amplitude ratio for sinusoidal inputs can be easily covered due to graphical demonstration for both simulated system and real system.
