A method for balancing a rotor of a rotary machine, wherein the rotor includes at least two rotor blades and a rotor shaft, includes receiving at least one measurement of either a load, an acceleration, or a displacement that pertains to at least one bending moment acting on the rotor shaft, determining at least one value of the at least one bending moment acting on the rotor shaft based, at least in part, on the received at least one measurement, and determining a pitch offset angle value of at least one rotor blade that facilitates reducing the at least one bending moment acting on the rotor shaft.

What is claimed is: 1. A method for balancing a rotor of a rotary machine, wherein the rotor includes at least two rotor blades and a rotor shaft, said method comprising:receiving a measurement of at least one of a load, an acceleration, and a displacement that pertains to at least one imbalanced load acting on the rotor shaft; anddetermining a pitch offset angle value of at least one rotor blade that facilitates reducing the at least one imbalanced load acting on the rotor shaft, wherein the at least one load imbalance is caused by at least one of a mass imbalance in the at least two rotor blades, a geometrical irregularity in the rotor, a difference in aerodynamic geometry between the at least two rotor blades, and a difference in a pitch angle zero point between the at least two rotor blades.
