Abstract :
This paper presents an optimal voltage synthesis technique for a satellite application to maximize system performance subject to energy budget. A period of a satellite´s orbit is partitioned into several independent regions with different characteristics such as type of computation, importance, performance requirements, and energy consumption. Given a periodic energy recharge model, optimal voltages for the regions are synthesized such that the overall performance is maximized within the energy budget in the period.
