Web23 okt. 2024 · This paper considers a feedback control law that achieves attitude stabilization for Earth-pointing spacecraft using only magnetorquers as torque actuators. The control law is proportional derivative (PD)-like with matrix gains, and it guarantees asymptotic stability. The PD matrix gains are determined through the numerical solution … WebOne routine operation that most spacecraft must perform is stored angular momentum management to maintain fully usable momentum exchange actuators. The execution of this activity may be...
WebTo solve the magnetic attitude control problem of a bias momentum satellite, a controller design method based on genetic algorithms (GAs) is addressed. The pitch loop of the satellite is controlled by a bias momentum wheel, while the roll/yaw loops are stabilized by two magnetic torquers which are installed along their respective axes. Momentum … Web1 jan. 2024 · Abstract: We revisit attitude stabilization for inertial pointing spacecraft endowed with magnetic actuators. Under mild assumptions on the time-variability of the …
Web1 aug. 2004 · The problem of inertial pointing for a spacecraft with magnetic actuators is addressed and an almost global solution to the problem is obtained by means of static attitude and rate feedback. A local solution based on dynamic attitude feedback is also presented. Simulation results demonstrate the practical applicability of the proposed …
