Satellite attitude rapid maneuver switching control method

The invention discloses a satellite attitude rapid maneuver switching control method. A used switching parameter delta is used for judging an amplitude of an angular speed to carry out switching, so that compared with an angular position judging method, the rapid and flexible satellite attitude switching control method can avoid the problem that a satellite attitude cannot enter closed-loop control stage due to factor influence of external interference, inertia perturbation and the like; a used switching parameter gamma can avoid partial time during which a small angular speed is included in when maneuver is started, and avoids the satellite attitude directly entering a closed loop stage during the time when maneuver is started, wherein the partial time meets the condition that the absolute value of omega is less than or equal to delta; and a used switching parameter eta can be used to consider engineering constraint and implement automatic switching of acceleration, constant speed, deceleration and closed loop of the attitude maneuver according to received relative attitude quaternion information. The satellite attitude rapid maneuver switching control method realizes accurate switching; rapid attitude maneuver control can be implemented; maneuver around a quaternion Euler axis is implemented; and path planning and time optimization of attitude maneuver are implemented.
