摘　　要：无人机在以机群编队飞行的模式下,受编队飞行环境的影响,使得无人机在保持编队队形和协同编队一致性控制问题上存在技术难度。对编队飞行采取自适应控制进行设计,根据编队间距以及长僚机位置姿态信息为编队控制器生成速度和航向角的指令信号。分两种情况进行研究:一类是气动耦合干扰参数未知情况下编队控制律设计,另一类是干扰因素未知情况下的编队控制律设计。通过最基本的构造李雅普诺夫函数,从理论上分析编队飞行间距误差最终收敛于0,编队运动稳定,编队队形可以得到保持;最后用仿真算例验证本文辨识方法的有效性。Abstract：Under the UAV formation flight mode, there would be difficulty in consistency control ol keeping and coordinating formation due to the restricted formation flight environment. This paper applies the adaptive control strategy to design the formation flying and generate the speed or heading angle command signal of the controller based on the formation distance and long wingman position and attitude information. It studies two cases： forma- tion control law design with the aerodynamic coupling interference parameters unknown; formation control law design with confounding factors unknown. From the theoretical analysis, it finds out that the formation flying dis- tance error eventually converges to 0 and formation movement stability or formation flying can be maintained by using the basic Lyapunov function structure. The simulation example is then used to prove the efficiency of this parallel distribution algorithm.
