Satellite High Angular Rate Cooperative Damping Strategy with Attitude Control Thrusters
Regarding the issue of high angular velocity damping in satellites,a velocity damping strategy using attitude control thrusters is studied,which is token into account the design principles of fewer startup times and longer startup times for attitude control thrusters.A collaborative damping strategy is proposed,which combines the three-axis simultaneous damping method with the single axis sequential damping meth-od.When the angular velocity of any two axes of the satellite exceeds the set angular velocity threshold,a Schmidt trigger is used for three-axis simultaneous damping to achieve effective damping of the satellite's large angular velocity.On the contrary,single axis damping is used in order of angular velocity to reduce the number of times that the thruster is turned on or off.The numerical simulation results show that the col-laborative damping strategy can effectively achieve satellite high angular rate damping and effectively reduce the number and duration of thruster startup.
