摘要： Provided are an attitude control system and method of a spacecraft of an artificial satellite that may enhance a maneuverability and a controllability by simultaneously applying a reaction wheel and a thruster among drive units used to maneuver an attitude of the spacecraft of the artificial satellite. The attitude control system may include: a thruster-based attitude controller which control firing time of thrusters mounted on the spacecraft; and a reaction wheel-based attitude controller controlling driving of a reaction wheel mounted on the spacecraft. The spacecraft may include a plurality of reaction wheels. When a defect occurs in the spacecraft due to a partial malfunction of the reaction wheels, an attitude maneuverability of the spacecraft may be corrected by simultaneously applying the thruster-based attitude controller and the reaction wheel-based attitude controller.

摘要： A reaction wheel momentum management method using a null space vector is provided. In accordance with this method, when any one of at least four reaction wheels used for triaxial control is made unavailable or degraded, a degraded wheel is used as long as possible for improving the mobility of the behavior of a satellite. The method provides momentum management for an N-number of reaction wheels W1, W2, . . . WN used for triaxial control of a satellite B by using a null space vector, and includes the steps of: (S10) measuring the current speed and momentum of the wheels in real time and comparing the measured current speed and momentum with a preset maximum speed and momentum; (S20) calculating a zero torque Tn based on a difference between the current speed and momentum and the maximum speed Wi,max and momentum Hi,max by the step (S10); (S30) adding the zero torque acquired by the step (S20) to a wheel torque Ta required for controlling and stabilizing the attitude of the satellite; and (S40) making the wheels reach an optimum bias momentum state by using the input torque of the wheels acquired by the step (S30).
