Modified Cross Feedback Control for a Magnetically Suspended Flywheel Rotor with Significant Gyroscopic Effects
Figure 7
Rotor speed root locus comparison for the MSR with the increase of the rotor speed. (a) Cross feedback control without phase compensation. (b) Cross feedback control with traditional phase compensation method. (c) Modified cross feedback control. Note: the arrowhead denotes the increased direction of rotor speed.
