Study of decentralized collaboration power control for spacecraft

Spacecraft have many components required for existence in orbit, e.g. subsystems for electrical power, thermal control, communication & data handling and attitude control, which are known as “BUS systems”. To increase the ratio of mission payloads in spacecraft, a compact and lightweight BUS system is demanded, in response to which JAXA has been studying the establishment of decentralized and collaboration power control. In this paper, we describe an algorithm of decentralized and collaboration power control and a test of an experimental model.
