  • Reducing vibration using QR decomposition and unconstrained optimization
    Patent number: 6567757
    Abstract: Determining adjustments to decrease vibrations caused by rotating blades includes receiving 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, where the adjustments include at least two different types of adjustments having different units of measure, 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, where the possible values for the adjustments results in the vibrations being less than a predetermined value and where the different types of adjustments are normalized according to a maximum amount of adjustment for each type of adjustment. The predetermined value may correspond to an expected value of all errors. The predetermined value may be increased in order to decrease the values for the adjustments that may be applied to the blades.
