Abstract

Described are systems and methods for monitoring and managing power sharing across multiple loads connected to a shared direct current (DC) bus. Embodiments of the present disclosure may be implemented to monitor and manage power sharing between multiple propulsion mechanisms (e.g., motors) of an aerial vehicle, such as an unmanned aerial vehicle (UAV). One or more shape functions establishing current limits as a function of the DC bus voltage may be determined for each load (e.g., propulsion mechanism/motor) of the multiple loads (e.g., propulsion mechanisms/motors) connected to the DC bus, and the current consumed by each load can be limited based on the DC bus voltage and each shape function.
