Flight simulation and control method of a unmanned aerial vehicle with regenerative fuel cells and solar cells for high altitude long endurance, and a control apparatus thereof

A flight control method for an unmanned aerial vehicle based on regenerative fuel cells and solar cells, comprising:

• an inputting step of receiving an input for a weight and a wing area of the unmanned aerial vehicle and water electrolysis performance of the regenerative fuel cells;
• a required energy calculating step of measuring a current speed and altitude of the unmanned aerial vehicle that is being flown to calculate lift force and thrust force of the unmanned aerial vehicle and drag force acting on the unmanned aerial vehicle and calculate output power and required energy of the unmanned aerial vehicle using the lift force, the thrust force, and the drag force;
• a calculating step of measuring energy generated by the solar cells installed in the unmanned aerial vehicle and measuring a current cell voltage of fuel cells included in the generative fuel cells to calculate energy generated by the fuel cells, amounts of hydrogen and oxygen consumed through the fuel cells, and an amount of water generated through the fuel cells, and calculating amounts of hydrogen and oxygen generated in a water electrolyzer included in the regenerative fuel cells and an amount of water consumed through the water electrolyzer using surplus energy except the required energy supplied to the unmanned aerial vehicle in the energy generated by the solar cells;
• and
• a deciding step of deciding whether or not energy that is generated in the fuel cells maintains a currently set flight control on the basis of the amounts of hydrogen and oxygen generated using the surplus energy.
