Experimental study of unbalanced rotors synchronization of the mechatronic vibration setup

Vladimir Boikov, Boris Andrievsky, Vitaly Shiegin

In the paper the results of experimental examination of self-synchronization and Sommerfeld effect both in the open-loop and the closed-loop control modes are presented. The experiments are fulfilled on the novel Multiresonance Mechatronic Laboratory
Setup (MMLS), which includes the unbalanced vibroactuators,
mounted on the spring-suspended platform, sensors, electrical motors and the computer interface facilities. It is shown that the closed-loop control makes it possible to stabilize the rotation speed more accurately, than the open-loop motors control. Some
additional effects, like low-frequency self-oscillations, may arise due to the integral (I) component of the closed-loop control action.
