Singularity-Free Momentum Generation with Non-Redundant Single Gimbaled Control Moment Gyroscopes
نویسندگان
چکیده
Two objectives dominate consideration of control moment gyroscopes (CMGs) for spacecraft maneuvers: High torque (equivalently momentum) and singularity-free operations. This paper adds to the significant body of research towards these two goals utilizing a minimal 3-CMG array to provide 646% singularity-free momentum performance increase spherically, compared to the ubiquitous pyramid arrangement skewed at 54.73". Spherical lH (1 CMGs-worth momentum) singularity free momentum is established with birectional lH and 2H in the third direction in a baseline configuration. Lastly, momentum space reshaping is shown via mixed skew angles. These claims are demonstrated analytically, then heuristically, and finally validated experimentally.

متن کاملGlobal Steering of Single Gimballed Control Moment Gyroscopes Using a Directed Search
A guided depth-first search that manages null motion about torque-producing trajectories calculated with a singularity-robust inverse is proposed as a practical feedforward steering law that can globally avoid (or minimize the impact of) singular states in minimally-redundant systems of single gimballed control moment gyroscopes. Cost and heuristic functions are defined to guide the search proc...

In this paper a new practical Attitude Control System is proposed, based on Control Moment Gyroscopes (CMG). These actuators can provide unique torque, angular momentum and slew rate capabilities to small satellites without any increase in power, mass or volume. This will help small satellites become more agile and maneuverable. Agility considerably increases the operational envelope and effici...
