Abstract:
A device for the radial attitude control of a rapidly rotating rotor supported in a contactless manner, the device comprising a sensor device for the continuous generation of rotor attitude signals and a control device for processing the rotor attitude signals, the control device including a controller that outputs a rotary-frequency-dependent output resultant signal, generated from the rotor attitude signals, for controlling the actuating device, wherein the resultant signal follows the rotary-frequent waveform of the controller output signal at frequencies below the resonance frequencies of the contactless support, wherein above these resonance frequencies the resultant signal increasingly follows the rotary-frequent waveform of the controller output signal only in the area of at least one of the two extreme values of the waveform, whereby the amplitude of the resultant signal is distinctly smaller than the amplitude of the rotary-frequency-dependent controller output signal, and wherein the resultant signal of the rotary-frequency-dependent oscillation maps superposed oscillations of the controller output signal that are low-frequency in comparison to it in a practically unchanged manner.
