This article focuses on the validation of a classical PID controller scheme for flexible spacecraft with regards to effect parameter uncertainty system stability and pointing precision. A high-fidelity simulation environment external disturbances was built in Simulink using control-oriented model an Earth-observing satellite appendage on-board microvibration sources orbit around planet. Then, c...

Space mission operations require flexible, efficient and reliable plan execution. In typical operations command sequences (which are a simple subset of general executable plans) are generated on the ground, either manually or with assistance from automated planning, and sent to the spacecraft. For more advanced operations more expressive executable plans may be used; the plans might also be gen...

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...

This paper presents the dynamic modeling and fuzzy sliding mode control for rigid-flexible multibody systems. To investigate the dynamic stiffening of rigid-flexible systems, a firstorder approximate model of a flexible spacecraft system is formulated by using Hamilton’s principles and assumed mode method, taking into account the second-order term of the coupling deformation field. For highly f...
