The chain pendulum consists of a cart connected to a belt and driven by a DC motor. Attached to this carriage is a unilaterally rotatable, inextensible and flexible chain whose deflection depends on the movement of the carriage. The aim of the experiment is to keep the natural oscillation of the chain, which is caused by external forces, under control.

Challenges for Teaching

  • Stabilization of the chain during maneuvers
  • Robustness with respect to disturbances

Application in Practice

  • Control of the oscillation behaviour of the cart and the chain attached to it
