摘要
This control module (22) of desaturation of the inertia wheels of an attitude control device (20) comprises a module of the actuation of the torques to be able to apply a spacecraft (10) in order to modify its orientation, is characterized in that it is capable of: - for each of the preceding passage, to estimate the gyroscopic torque the spacecraft (10) on the two orthogonal axes (xsat, zsat), and to estimate the disturbing torques applied to the spacecraft (10) on the two orthogonal axes (xsat, zsat); - for each current, to determine a first and second signals as a function of the gyroscopic torque and the estimated disturbing torques, and to apply the first and second signals to the system of the actuators to desaturate at least some of the inertia wheels when the spacecraft (10) is located in a portion of desaturation authorized.
