Summary:METHOD AND APPARATUS FOR DYNAMIC PRECOMPENSATION OF SOLAR WING STEPPING MOTIONS OF A SATELLITE This invention discloses a method for compensating for the disturbance torque on an orbiting satellite (10) caused by the slewing motion applied to the solar wings (16,17) of the satellite (10) to track the sun. The acceleration signals applied to the solar wings (16,17) in order to slew the wings are multiplied by an estimated inertia of the solar wings (16,17) to derive a control torque opposite to the disturbance torque applied to the satellite (10) by the slewing of the solar wings (16,17). The estimated control torque is added to the control torques from other disturbances. The added control torque is then applied to an actuation device (46) in order to actuate the satellite (10) into a desirable attitude.
