一种太阳能无人机降落阶段横桨功能实现策略

A Strategy for Realizing the Function of Horizontal Propeller in the Landing Stage of Solar UAV

太阳能无人机是临近空间飞行器领域的研究热点,针对太阳能无人机降落阶段对于螺旋桨保持横桨的需求,基于永磁交流伺服电机的磁场定向控制策略设计了一种横桨控制方法,将电机模拟为具备多圈传感器的伺服机构,对其进行轨迹规划,不仅可以灵活设计其减速曲线,也可以使用多圈的行程连贯地实现定位过程。经试验证明,该控制方法可靠有效,满足无人机的降落使用要求。

Solar unmanned aerial vehicle(UAV)is a research hotspot in the field of near space vehicles.Aiming at the demand of propeller to maintain horizontal propeller in the landing stage of solar UAV,a horizontal propeller control method was designed based on the magnetic field orientation control strategy of permanent magnet AC servo motor.The motor was simulated as a servo mechanism with multi-turn sensors,and the trajectory planning was carried out.The control method can not only flexibly design its deceleration curve,but also use multi-turn stroke to realize the positioning process coherently.Experiments show that the control method is reliable and effective,and meets the requirements of UAV landing.
