Experiment research of the mechatronic inerter based on active control

Abstract

Mechatronic damper, that is an electromagnetic damper, has a damping force in general. The damper complies with ball screw mechanism and generator. The damping force is depended on terminal resistance of the generator, and it is controllable. However, Dr. Zhu’s group researched about the mechatronic damper based on active control, it was called mechatronic inerter, which could get an inertia force by using a force feedback PID active control, and reported in simulation. In this paper, to confirm it and moreover get switchable inertia effect, vibration tests are carried out by using the mechatronic damper and another simple control method. Finally, it is clear from the experiments that inertia effect can be varied when current goes to the generator will be controlled.
