Algorithm of multiple observer-based synchronization
for time-varying two-rotor vibration system
Irina Kudryavtseva
In this paper an algorithm of multiple synchronization of two-rotor vibration unit with timevarying
payload is proposed. The performance of the proposed system is analyzed by computer
simulation for model of the 2-rotor vibration set-up consisting of two rotors driven by DC motors
and a rigid platform mounted on an unmovable base. A time-varying payload attached to a platform
allows one to study dynamics of material processing. Additional problem arises owing to incompleteness
of measurements: only rotor phases are available for measurement. To solve this
problem an observer (state estimator) is introduced into the system structure.
