Controlling deformations of a 3D-printed vibrating beam using stiffness modulation

This presentation will elaborate on the graduation project of Sander Roodink. The project aims to implement damping-injection on a vibrating motion of an FDM-manufactured beam by an energy-based control method. The system will use multiple, sensibly positioned embedded 3D-printed sensors as input. Two actuators are implemented in the system. One actuates the beam vibration while the other one can vary the stiffness of the beam. Because there are only two actuators, which are non-collocated with the sensors. A deformation model of the beam should be designed and implemented in the control-loop.

This project will result in a set-up of the complete controlled system. The test results will be analyzed, validated and discussed.
