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. Let's teach automatic control with Ball and Beam!


Apply control theory in real-life with ACROME Ball and Beam! The ball and beam system consists of a long beam together with a ball rolling back and forth on top of the beam. The long beam tilted by a servo. Our Ball and Beam System provides practicing the automatic control theory on a closed loop experiment. Controlling the position of a ball on a beam is one of the classical 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.
