Abstract: 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.
