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

Abstract

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 starting and generating integrated circuit unit stops supplying power; the direct current brushless motor outputs three-phase alternating current to the starting and generating integrated circuit unit, and the three-phase alternating current provides electric energy for airborne equipment and an airborne battery after being rectified and filtered. According to the control method, starting and generating are completed based on the control system.

Description

technical field [0001] The invention belongs to an unmanned aerial vehicle control system and method, in particular to an integrated control system for starting and generating electricity of an unmanned aerial vehicle and a control method thereof. Background technique [0002] In the field of traditional unmanned aerial vehicles, the start of the aero-engine for unmanned aerial vehicles is completed with the help of the starter motor and the starter device. After the engine is started, the starter device will no longer work, and the generator motor and the generator device will work together to meet the aircraft's battery life requirements. . [0003] The starting of the engine is to use the starter motor connected to its machinery or transmission to drive the engine to ignite under high-speed motion. After the engine is started, the chemical energy of gasoline and other fuels can be converted into mechanical energy to generate power for the drone to fly. There are many ki...
