Optimal Control Techniques for Spacecraft Attitude Maneuvers
The capability of attitude maneuvers and attitude tracking for spacecrafts is required in the current sophisticated space missions. In short, it is to obtain command requirements and attitude orientation after some form of control. With the development of space missions, the ability of rapid and energy-saved large-angle attitude maneuvers is actively expected. And the high requirements for the ...
متن کاملNonlinear Attitude Control for a Rigid Spacecraft by Feedback Linearization
Attitude control law design for spacecraft large angle maneuvers is investigated in this paper. The feedback linearization technique is applied to the design of a nonlinear tracking control law. The output function to be tracked is the quaternion attitude parameter. The designed control law turns out to be a combination of attitude and attitude rate tracking command. The attitude-only output fu...
متن کاملRobust Optimal Control of Flexible Spacecraft During Slewing Maneuvers
In this paper, slewing maneuver of a flexible spacecraft with large angle of rotation is considered and assuming structural frequency uncertainties a robust minimum-time optimal control law is developed. Considering typical bang-bang control commands with multiple symmetrical switches, a parameter optimization procedure is introduced to find the control forces/torques. The constrained minimizat...

which clearly reduces to the vacuum case de ned by Eq. (3) as ̄ ! 0. The velocity- ight-path-angle pro le is shown in Fig. 2 for a range of drag parameters ̄ . It can be seen that as the effect of air drag increases, the trajectory curves more quickly toward the local vertical.Because the effect of drag is to increasethe effectivethrustweight ratio of the vehicle, the descentmaneuvermay be com...
متن کاملNonlinear H ∞ for Spacecraft Attitude Control
This paper presents a nonlinear H∞ state feedback attitude control design method for spacecraft large angle maneuvers, which is subject to moment-of-inertia (MOI) uncertainty. Moreover, the operation of attitude maneuver is affected by external disturbances. The attitude control design thus employs a nonlinear H∞ method to achieve stability and robustness so that both MOI uncertainty and extern...
