Synthesis of control system and control algorithm for compensating for the residual imbalance of a complex flexible rotor on electromagnetic suspension

Abstract

A system and algorithm for controlling a complex flexible rotor on active magnenic bearings have been proposed that make it possible to significantly reduce the amplitude of rotor vibrations at critical frequencies. The algorithm combines the identification of the forces of inertia caused by the residual imbalance and the formation of control actions compensating these forces. The effectiveness of the synthesized control system and control algorithm has been illustrated by computer simulation.
