Ball and Beam

1 DOF Control Platform for Teaching and Research

ACROME Ball and Beam System is ideal to introduce students to the fundamental and intermediate principles of controls.


Apply control theory in real-life with ACROME Ball and Beam! Controlling the position of a ball on a beam is one of the main problems of control theory. Ball and Beam System can be used for a wide range of control system design implementations from basic linear controllers to advanced nonlinear methods. Students are able to understand system design approaches with Ball and Beam's learn-by-doing method. With the help of the courseware, they can distinguish effects of linearizations, assumptions and modeling errors due to the differences between simulations and real world experiments.
