A rotary machine (10) includes a rotor (18) including a hub (22), at least two rotor blades (24) coupled to the hub, and a rotor shaft (28, 30) coupled to the hub for rotation. At least one blade pitch actuator (56) is coupled to at least two rotor blades for controlling an angle of pitch of at least two rotor blades. At least one sensor (48, 50) is configured to measure at least one of a load, an acceleration, and a displacement that pertains to at least one bending moment acting on the rotor shaft. A processor (64) is coupled to at least one blade pitch actuator and coupled to at least one sensor. The processor is configured to balance the rotor by receiving (102), from at least one sensor, at least one measurement of either a load, an acceleration, or a displacement that pertains to at least one bending moment acting on said rotor shaft. Determining (104) at least one value of at least one bending moment acting on the rotor shalt based, at least in part, on the received at least one measurement and determining (106) a pitch offset angle value for at least one rotor blade that facilitates reducing the at least one bending moment acting on said rotor shaft. |
