基于数据驱动的小型柔性翼飞行器控制研究

柔性翼在阵风干扰下的被动变形有助于降低其对飞行器运动的影响，设计采用柔性翼的小型飞行器被认为是解决小型飞行器易受阵风干扰问题极具潜力的方案.同时，翼面可卷曲的特性也使得该类飞行器满足单兵便携式武器装备易携带的要求.考虑一种无副翼柔性翼飞行器区别于常规飞行器布局的特点，为解决由飞行试验数据分析得出的全动平尾舵面出现非线性饱和问题以及同时利用平尾舵面控制滚转俯仰通道引起的耦合问题，设计了一种基于数据驱动的无模型自适应控制器方案.数值仿真结果证实了针对该型无副翼柔性翼飞行器的姿态控制，所设计的控制器较传统单通道PID控制器控制效果更好. 

Research on Data Driven Control of a Small Flexible Wing Aircraft

The passive morphing of the flexible wings caused by the gust of wind will reduce the unstable motion disturbance to flight. The small flexible wing aircraft is believed to be a solution to the problem of small aircraft being susceptible to gust disturbance, as well as meeting the characteristics of portable weapons. However, due to the fact that the small flexible wing aircraft has no ailerons and other characteristics different from the conventional aircraft layout, the two problems emerge from the flight test data analysis-the all-moving tail control efficiency is low and prone to nonlinear saturation problems, and the coupling problem caused by using the tail to simultaneously control the pitch and roll channel. A data-driven model-free adaptive controller scheme was presented. The simulation results prove that the presented controller has better control effect than the traditional single-channel PID controller.
