摘　　要：现有扑翼微飞行器的悬停控制方法,多通过机顶扑动翼的水平运动来获取升力,由于依靠水平扑动弦向扭转形变获取的升力十分有限,导致微飞行器悬停时间短、稳定性差、所携载荷有限。提出一种利用紫外加工的扑翼微飞行器悬停控制方法,首先在微飞行器的加工制造方面运用了紫外加工切割技术,实现微米尺度的加工,提高设备的精度和性能;依据空气动力学特性,分析扑翼微飞行器的上升和悬停机理,并获取一个动力学数学模型;基于该模型和仿生翻转翼悬停方式,计算升力、阻力系数和迎角的变化,实现对扑翼微飞行器的悬停控制。仿真实验表明提出的控制方法,能够有效提高悬停的稳定性和时长、在微飞行器所携载荷方面也有较大优势。Most of current hovering control of flapping wing MAV gets lifting power through the horizontal motion of top flapping wing. Because of the limited lifting power,the MAV has short hover time,poor stability and limited load.Therefore,a new method based on UV processing is put forward. Firstly using UV cutting technology in the machining of micro aircraft manufacturing to realize micrometer processing which is to improve the accuracy and performance of the equipment. On the basis of the aerodynamics,analyzing rise and hover mechanism of flapping wing MAV to obtain a dynamic mathematical model. Based on this model and bionic wing hovering turnover,calculate the changes of lift and drag coefficient and angle to achieve hover control of flapping wing MAV. The simulation shows that this method can effectively improve the stability and time of hovering,and also has a great advantage in loads.
