Summary:The magnetic control algorithm is a very important means in the satellite control system, especially for satellites without thrusters. When the satellite generates a large angular velocity due to the separation of satellite and rocket or abnormal interference, the use of magnetic torque devices for magnetic damping control can simply and effectively reduce the angular velocity. This paper studies the engineering realization of the magnetic damping algorithm, analyzes the limiting conditions of the application of the magnetic damping algorithm under the control cycle and time delay. The minimum angular velocity that the magnetic damping algorithms can achieve and the maximum angular velocity that the algorithm can effectively work will be given. The analysis results are of great value to engineering applications.
