The invention discloses an intelligent suppression method for micro-vibration of a flywheel set of an in-orbit satellite. Relates to the technical field of spacecraft systems, in particular to the technical field of intelligent suppression of micro-vibration of flywheel sets of on-orbit satellites. The method effectively solves the problem that quantitative indexes of the vibration isolation effect are lacked in the temperature control process when the flywheel set rotating speed working condition coverage is small, and the calculation efficiency and precision are improved. The method comprises the following steps: extracting frequency domain vibration disturbance data of a flywheel at a specified rotating speed; acquiring the displacement response of the frequency domain of the sensitive component under unit disturbance vibration; acquiring the displacement response of the sensitive component in the time domain under the disturbance vibration of the flywheel group; calculating an actual image motion value; quantitative characterization of the performance of the vibration isolator under the working condition of the specified rotating speed is calculated through the actual image motion value; constructing and training a rotation speed working condition-vibration isolator performance proxy model; and the micro-vibration of the in-orbit satellite flywheel group is intelligently inhibited.
