基于数据驱动的小型柔性翼飞行器控制研究

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.
