Software-Based Intelligent Power Storage and Management:: An Embedded Control System for Satellite Electrical Power Subsystem (EPS)

The need for reliable electrical power supply is very primary for satellites to navigate their orbits and achieve their varied mission objectives. The Satellite Electrical Power Subsystem (EPS) generates, stores, conditions, controls and distributes power for satellite’s housekeeping operations. This publication examines the design of a software-based Intelligent Power Storage and Management Control System (IPSMCS) for application in the intelligent coordination of power storage, power savings, payloads switching and battery temperature control in the EPS of a satellite. The IPSMCS achieved an improvement over the conventional satellite power management and control systems in terms of system’s size reduction, self-contained intelligence, flexibility and improved system response to power emergencies.
