The invention provides a vertical take-off and landing fixed-wing unmanned aerial vehicle propeller drag reduction device and a control method thereof. The device is characterized in that the device comprises a vertical take-off and landing propeller, a linear Hall motor position sensing unit, a motor driving unit, an operation processing unit and a wind speed sensor unit; the operation processing unit outputs an adjustment instruction obtained after calculation and analysis to the linear Hall motor position sensing unit according to the received sensing result value, and finally the rotor resistance generated in the flight of the vertical take-off and landing fixed-wing unmanned aerial vehicle is reduced. According to the invention, the minimization of the wind resistance of the rotor wings in the cruise state in all time periods can be realized, so the energy consumption is greatly reduced, and the overall endurance time of the unmanned aerial vehicle is prolonged; the calculation method is simple and convenient, the structural design is scientific and reasonable, PID control is very easy to realize, and the overall structural complexity of the unmanned aerial vehicle is reduced; and the PID scheme is timely in response, so that later maintenance and management are facilitated.

    本发明提供一种垂直起降固定翼无人机螺旋桨减阻装置及其控制方法,其特征在于,包括:垂直起降螺旋桨、线性霍尔电机位置感知单元、电机驱动单元、运算处理单元以及风速传感器单元;所述运算处理单元根据接收到的感知结果值,向所述线性霍尔电机位置感知单元输出计算分析后得到的调整指令,最终实现减小垂直起降固定翼无人机飞行中产生的旋翼阻力,本发明可实现巡航状态下全时段的旋翼风阻最小化,大大降低了能源消耗,延长了无人机的整体续航时间;计算方法简便,结构设计科学合理,采用PID控制非常易于实现,降低了无人机的整体结构复杂度;且PID方案响应及时,易于后期的维护和管理。
