Application Research on Dynamic Balance Control for Spaceborne Large-Scale Rotary Payload.

The dynamic unbalance of the rotor on a satellite produces unexpected disturbing torque and affects satellite attitude, so the amount of dynamic unbalance must be controlled in the high quality movement control of the satellite. The flexible multi-body dynamics model is built, meanwhile, residual disturbing torque of the rotor is analyzed by using the dynamic balance test, the control method and process for dynamic balance of large-scale rotary payload are proposed. Finally, practice engineering application and on orbit telemetry demonstrate that the control method and process of dynamic balancing are feasible and effective. [ABSTRACT FROM AUTHOR]
