Description
The data contains the measurement data of the passive performance and the active vibration control of the rotor system as well as the transfer functions from our FEM model. The used rotor test-rig has an active bearing which comprises two piezo actuators. We implemented a model-based LMS control combined with IFF to eliminate the forces in the first bearing plane. The performance of this algorithm is compared to a rotor-model-free implementation of the LMS in combination with IFF which is extended by the frequency domain approach. We furthermore added an algorithm to compensate for the time delay caused by the used transformation. All three controllers are investigated on the test-rig. We then use the rotor-model-free control to estimate the transfer functions from actuator voltages to disc displacements and bearing forces. Two run-outs are performed to do so, one with IFF and one with IFF in combination with the rotor-model-free frequency domain LMS. Read the publication for more details.
