Determining adjustments for rotating blades includes measuring a plurality of vibration values corresponding to vibrations caused by the blades, providing coefficient of vibration data that corresponds to effects on vibration caused by adjustments to the blades, applying the coefficient of vibration data to the vibration values, and solving for possible values for the adjustments that may be applied to the blades, wherein the possible values for the adjustments are constrained to be greater than a first predetermined value or zero. The adjustments may include at least one of hub weights, blade tabs, PCR adjustments, and blade tip weight adjustments. Measuring vibrations may include obtaining signals from a plurality of accelerometers. Determining adjustments may also include performing an FFT on the vibration data, where the data indicating effects on vibration is provided in the frequency domain. Applying the data to the vibration values may be performed in the frequency domain.
