The attitude matching transfer alignment is sensitive to the wing flexibility. If the model of the wing flexibility is fault, the Kalman filter performance of the attitude matching transfer alignment should be deteriorated. The H∞ filter is robust to the uncertain disturbance of the system. In this paper, the H∞ filter for the attitude matching transfer alignment is designed and the wing flexibility is considered as the uncertain disturbance measured in the attitude matching transfer alignment. Simulation results show that the H∞ filter for the attitude matching transfer alignment can accomplish the transfer alignment within about ten seconds and the accuracy of the transfer alignment can be less than five angular minutes without the model of the wing flexibility.
