Abstract
A device for the attitude control of a rapidly rotating rotor, especially a spinning rotor, supported in a contactless manner. The device comprises a sensor device for the continuous generation of rotor attitude signals and a control device ( ) that processes the rotor attitude signals and continuously outputs a correcting variable to an actuating device that influences the rotor attitude. The control device ( ) is set up in such that the rise of the waveform of a resultant signal from which the correcting variable is derived is limited to a maximum amount and, upon the occurrence of higher oscillation frequencies of the rotor attitude signals, the oscillation amplitudes of the resultant signal for the actuating device can at the same time be reduced with a small phase error. The device makes it possible to achieve low energy consumption, an expanded controllability and greater operational safety in a simple manner.
