Adaptive Synchronization Control of the Magnetically Suspended Rotor System

An adaptive controlapproach to the implementation of synchronization control forthe magnetically suspended rotor system is presented. The controlsystem enables a translatory mode for the whirling rotor alongthe bearing axes, thereby eliminating the gyroscopic effectsthat can vastly degrade the rotor stability at high speeds. Thecontrol method features the integration of adaptive control andcross feedback control for the electromagnetic circuit, in whichan adjustment system is trained to tune the adaptation parametersto minimize the differential errors of state variables throughouta cross coupling controller. Under this control process, thecontrol variables are updated in a way to suppress the conicalmodes against the gyroscopic forces. This paper develops twokinds of synchronization control algorithms in conjunction withan optimization design, and the simulation of synchronizationcontrol for a magnetically suspended rotor system is presented.
