A distributed energy management strategies of fuel-cell electric propulsion UAV based on multi-agent system

Distributed electric propulsion technology is expected to further improve flight efficiency and the energy conversion efficiency of the propulsion system of aircraft. Fuel-cell combined with an electric storage system (ESS) such as a battery can increase the flight endurance and reduce the noise of aircraft to realize the zero-emission. In this paper, a distributed electrical power system architecture is presented according to UAV under research projects, and a multiple agent-based dynamic energy management strategies (EMS) with primary droop control loop is proposed based on flighting power profile of UAV. Finally, With Typhoon-HIL604 and RT-LAB5700, A real-time simulation testing platform is built for distributed electric propulsion aircraft composed of four groups of fuel cells and lithium battery units.
