Dynamic balance type fuel cell unmanned aerial vehicle energy management method

The invention discloses a dynamic balance type fuel cell unmanned aerial vehicle energy management method. Aiming at an unmanned aerial vehicle hybrid power supply system taking a fuel cell as a mainpower supply and a lithium cell as an auxiliary power supply, multi-objective optimization energy management is performed based on fuel cell hydrogen consumption estimation on the premise of knowing the total hydrogen amount of the fuel cell, and the optimization objectives are respectively the hydrogen consumption rate (consumed hydrogen/total hydrogen) of the fuel cell and the energy utilizationrate (consumed electric quantity/total electric quantity) of the lithium cell. According to the method, the two objectives can keep dynamic balance, the situation that the electric quantity of one power supply in the hybrid power supply is exhausted firstly is avoided, the stability of the hybrid power supply system of an unmanned aerial vehicle can be maintained, and accordingly, the dynamic characteristic of the unmanne
