[0002] Solar-powered drones have the characteristics of light weight and long flight time. At present, solar-powered drones are gradually developing towards large-scale design. There are already solar-powered drones with a wingspan of 60m that have completed low-altitude autonomous flight. Large-scale solar-powered drones have solar cells. Large, limited by the volume and weight of the unit MPPT and heat dissipation, the current optimal maximum power point tracking (Maximum Power Point Tracking, MPPT) module power is about 300W, and the corresponding managed solar cell area is about 1m 2 Therefore, there are many MPPTs and power controllers for large-scale solar UAVs, up to dozens or even hundreds. The current MPPT module control is fully realized by the power controllers of solar UAVs. One power controller controls 3 Group MPPT module, according to the MPPT output voltage and current control its on and off, however, this method is decentralized and independent of each other, can not consider the energy storage battery voltage level and charge and discharge current, airborne task load for power demand, that is, it cannot be coordinated The problem of global control

The invention discloses a control method and device for a solar unmanned aerial vehicle. Judgment logic and control of an energy management system of the solar unmanned aerial vehicle and a flight task are achieved through a flight control and management computer of the solar unmanned aerial vehicle. The flight control and management computer controls the action of the solar unmanned aerial vehicle according to the voltage and current output by an MPPT controller of the solar unmanned aerial vehicle, and / or the voltage and charging and discharging current of an energy storage battery pack, and / or task load information, and / or the current flight task of the solar unmanned aerial vehicle. According to the method and the device, the problems that power supply controllers are dispersedly and mutually independent in control and cannot be comprehensively and globally controlled are solved, and meanwhile, the ground personnel intervention and the working pressure can be reduced.
