Robust Active Vibration Control of Flexible Rotors Using Piezo Actuators as Active Bearing

摘要

For the active vibration control of low natural bending frequencies of rotors different control concepts using piezo actuators at the bearings of a rotor are presented. Regarding practical applications actuator requirements are defined. Further the advantages of robust control, including the modeling of uncertainty and parameter changes by the method of μ-synthesis are briefly presented. A simple test rig is used to show the results of experimental investigations.
