On-orbit debugging method for unbalanced amplitude and phase of large-inertia rotating part of satellite

The invention discloses an on-orbit debugging method for unbalance amplitude and phase of a large-inertia rotating part of a satellite, and aims to solve the problem that periodic disturbance torque caused by unbalance of the rotating part is difficult to directly compensate by an attitude and orbit control subsystem and can directly influence the attitude stability index of the satellite. Dynamic and static imbalance of the rotating part are obtained by ground measurement, estimated values of amplitude and phase of disturbance torque generated by dynamic and static imbalance are given, and momentum wheel control instruction voltage is acquired. A momentum wheel feed-forward compensation method is adopted, an estimated value of a feed-forward command voltage debugging parameter is obtained, on the basis of the obtained estimated value of the debugging parameter, on-orbit injection fine tuning of the feed-forward command voltage debugging parameter is carried out, and the angular velocity amplitude of the sate
