| Summary: | Momentum changing actuators like reaction wheels and control moment gyros are generally used for spacecraft attitude
control. This type of actuators produces force and torque disturbances. These disturbances must be reduced since they
degrade the quality of spacecraft attitude control. Major disturbances are mainly due to static and dynamic imbalances.
This paper gives attention to the reduction of the static and dynamic imbalance. Force/torque measurement system is
used to measure the disturbance of the test reaction wheel. An identification method for the location and magnitude of
the imbalance is suggested, and the corrections of the imbalance are performed using balancing method. Through balancing,
the static and dynamic imbalance is remarkably reduced. |
