Planar, Time-Optimal, Rest-to-Rest Slewing Maneuvers of Flexible Spacecraft
The control problem of time-optimal, rest-to-rest slewing of a flexible spacecraft through a large angle is considered. The flexible spacecraft is modeled as a linear, elastic, undamped, nongyroscopic system suitable for analysis of planar rotational maneuvers. Minimum-time open-loop planar maneuvers are studied. The control histories are found to be bang-bang with multiple switches in each con...
متن کاملTime-optimal Rest-to-rest Slewing of Multi-mode Flexible Spacecraft Using Zvd Robustness Constraints
A procedure for obtaining robust time-optimal command profiles for multi-mode flexible spacecraft is presented. The command profiles are required to move a spacecraft from rest-to-rest with zero residual vibration. Furthermore, the commands are subject to a robustness constraint in an attempt to keep the residual vibration at a low level in the presence of modeling errors. The robustness constr...
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...
متن کاملPreliminary Design of Spacecraft Attitude Control with Pulse-Width Pulse-Frequency Modulator for Rest-to-Rest Maneuvers
In this paper, the preferred region of design parameters for quasi-normalized equations of single-axis attitude control of rigid spacecraft using pulse-width pulse-frequency modulator (PWPFM) is presented for rest-to-rest maneuvers. Using the quasi-normalized equations for attitude control reduces the system parameters, that is, the moment of inertia, the filter gain, and the maximum torque of ...
متن کاملNear-Minimum Time Optimal Control of Flexible Spacecraft during Slewing Maneuver
The rapid growth of space utilization requires extensive construction, and maintenance of space structures and satellites in orbit. This will, in turn, substantiate application of robotic systems in space. In this paper, a near-minimum-time optimal control law is developed for a rigid space platform with flexible links during an orientating maneuver with large angle of rotation. The time opti...
