Discretization Effects in Speed-Gradient Two-rotor Vibration Setup Synchronization Control

Abstract

This paper is devoted to the study of the influence of digitalization and discretization on the speed gradient algorithm operation for the multiple synchronization control of vibration setup rotors. The paper presents results of numerical simulation based on the system dynamics equations and approximate values of vibration setup parameters. The simulation results show that an increase of the discretization sampling step leads to a disruption of the multiple synchronization mode up to the stability loss.
