Satellite alignment control system and method

The invention provides a satellite alignment control system and method. The system comprises a microcontroller, a driver, a motor, a gyroscope and an inertial navigation system. The microcontroller is used for processing data acquired by the inertial navigation and the gyroscope to obtain attitude information of the carrier, performing coordinate transformation on the attitude information, converting three-axis disturbance of the carrier into two-axis tracking parameters including azimuth and pitching, and controlling the driver to drive the motor to act based on the two-axis tracking parameters; the motor comprises an azimuth motor and a pitch motor which are used for adjusting the azimuth angle and the pitch angle of the antenna respectively. According to the method, the three-axis disturbance data generated in the carrier movement process are processed through coordinate conversion, two-axis change data based on the azimuth and pitching are obtained, under the condition that an existing control system is s
