Unmanned aerial vehicle starting and generating integrated control system and control method thereof

The invention belongs to an unmanned aerial vehicle control system and method. Starting and power generation of an existing unmanned aerial vehicle engine are composed of two independent devices and control systems of the two independent devices, which increases the weight of an unmanned aerial vehicle body and increases the complexity and instability of an avionics system in the starting and power generation processes. The invention provides an unmanned aerial vehicle starting and generating integrated control system and a control method thereof. The system comprises an engine, a direct current brushless motor, a starting and generating integrated circuit unit and a starting battery; the direct current brushless motor is coaxially connected with the output end of the engine; during starting, the starting battery supplies power to the starting and generating integrated circuit unit; the direct current brushless motor drives the engine to rotate to the starting rotating speed; during power generation, the star
