The invention discloses an attitude maneuver method for adaptive angular momentum amplitude limiting adjustment. The attitude maneuver method comprises the following steps: acquiring attitude quaternion deviation and angular velocity deviation of a satellite body; according to the attitude quaternion deviation of the satellite body, a three-axis attitude maneuver angular velocity amplitude limiting value is obtained; obtaining a three-axis quaternion deviation amplitude limit value of the satellite body according to the three-axis attitude maneuvering angular velocity amplitude limit value of the satellite body; calculating attitude quaternion deviation of the satellite body after vector amplitude limiting according to the three-axis quaternion deviation amplitude limiting value of the satellite body; and according to the three-axis quaternion deviation and the angular velocity deviation of the satellite body after vector amplitude limiting, a three-axis instruction control moment is obtained. On the premise that the angular momentum of an executing mechanism in the maneuvering process does not exceed the output capacity, the angular momentum can be utilized and executed to the maximum degree, and meanwhile three-axis simultaneous maneuvering in place is achieved.
