Abstract:
Rotors with a high polar moment of inertia cause a high gyroscopic effect dependent on the angular velocity. If such a rotor is stabilized by active magnetic bearings (AMB) the development of the control structure requires often complex control approaches. The split up of the eigen-frequencies, caused by the gyroscopic effect can show stability problems for high speeds. However, for industrial applications the main share is based on conventional PID controllers. To close the gap between the control approaches, this paper uses the computed torque method to decouple the rigid body system.
