Abstract
In this paper we develop energy-metrics that are in-line with true energy costs incurred when performing a slew using reaction wheels. These energy-metrics are incorporated in constrained nonlinear optimal control formulations, which enable detailed analysis on the relationship between transfer-time and energy to be performed. Through numerical simulations, a nonlinear relationship between transfer time and minimal energy is used to help explain the tradeoff between transfer time and energy consumption. This analysis can provide important information for design and operations. In examining the relationship between transfer-time and minimal energy, we also analyze the difference between offeigenaxis and conventional eigenaxis maneuvering. It is demonstrated that, by deviating from rotations about an eigenaxis the transfer-time may be significantly decreased but without incurring more energy than an eigenaxis maneuver. Analogously, energy may be reduced for an eigenaxis maneuver.
