This report results from a contract tasking University of Surrey as follows The Grantee will investigate three areas concerning energy storage and attitude control systems ESACS for small satellites 1. Use of small satellite reference models to determine the relative scales for a combined variable speed control moment gyroscope VSCMG energy storage ES system. 2. Explore potential imbalances, derive mathematical descriptions of ESACS-imbalance systems and model the ESACS system in MATLABSimulink. 3. Construct experimental hardware for power conversion demonstration An experimental VSCMG system will be used to demonstrate combined attitude control and energy storage. The imbalances modeled in 2. will be replicated in the experimental hardware. Derived control solutions to the imbalance problem will be implemented and validated in the experimental hardware.
