Redundant flywheel set angular momentum self-management method

The present invention discloses a redundant set of angular momentum flywheel method of self-management. Periodic law three-axis stabilized satellites use the external disturbance torque provided unloading cycle T, and inside and outside disturbance torque estimated unloading cycle accumulated angular momentum HI (T); The HI (T) setting the initial value H0 of angular momentum synthesized; the initial work working wheel set or wheel set after reconstruction troubleshooting determining an operational target value of the target angular momentum wheel set hZ angular momentum zero motion space (t) and the impeller group H; hZ H0 and determine the operating wheel set according to offload target angular momentum h (0); unloading time by a jet control and the wheel rotational speed control to the angular momentum of the working set of wheels is controlled to offload target angular momentum h (0); non unloading time, in accordance with the zero motion control law working wheel set angular momentum to control the angular momentum of the working wheel set target value h (t). The present invention can be set in angular momentum of the flywheel inclusive maximum optimization unloading direction, save fuel, jet control without unloading cycle occurs flywheel component non re-configuration.
