Abstract
A system and method for controlling rotor dynamics at a rotor assembly. The system includes a magnetic actuator and a controller. The magnetic actuator is positioned in magnetic communication with the rotor assembly and is configured to obtain a measurement vector corresponding to the rotor assembly and a measurement vector indicative of a rotor dynamics parameter. The magnetic actuator is further configured to selectively output an electromagnetic force at the rotor assembly. The controller is configured to store and execute instructions. The instructions include outputting, via the magnetic actuator, a baseline electromagnetic force to the rotor assembly; obtaining the measurement vector at the rotor assembly from the magnetic actuator; determining non-synchronous vibrations corresponding to the rotor assembly based at least on the measurement vector and a rotor speed of the rotor assembly; determining cross coupled stiffness corresponding to the rotor assembly based at least on the measurement vector, the rotor speed, and a predetermined rotor dynamics model of the rotor assembly; determining an adjusted electromagnetic force of the rotor assembly based at least on the cross cou…
