The feedback system uses a PI controller with harmonic suppressors in parallel to specifically target perturbations at the mains frequency and its harmonics. This report will present the results of the commissioning of the FOFB system demonstrating a reduction in the integrated RMS motion up to 300 Hz by 75% to 90%.
