Rotor displacement curve with and without AFC.

Caption

After the ISA converges, the rotor vibration amplitude Vin is gradually reduced. in V drops from 11.74 um to 2.70 um, decreasing by 77.0%. Performing FFT analysis to the rotor displacement, the 1st order vibration drops from 11.50 um to 2.54 um, decreasing by 77.9%. The 3rd order vibration drops from 1.09 um to 0.37 um, decreasing by 66.1%. Comparing the rotor displacement with and without AFCs, vibration performance is significantly improved by the AFCs.
