Abstract

The stability analysis of a rotor system with electromagnetic control forces is investigated. The formulas for the electromagnetic forces between the stator and rotor of the electromagnetic actuator are derived with respect to the displacements of the journal center and coil currents. The minimum setting values of the controller, and the relationship between mode shapes at the positions of sensors and actuators of the system, are given by using a perturbation method and Routh–Hurwitz theory.
