本文考虑了在阵风干扰存在的情况下对非常灵活的飞机的控制。纵向轨迹跟踪是使用具有 PID 或滑模外环控制器和动态反演内环控制器的分层控制方案来执行的。基于系统降阶线性模型的线性二次高斯控制器用于跟踪横向命令。闭环响应在带有阵风扰动的完全非线性模拟中得到证明。最后，我们演示了副翼的协调控制，以减少机翼曲率偏离配平值的偏差。
This paper considers control of a very flexible aircraft in the presence of gust disturbances. Longitudinal trajectory tracking is performed using a hierarchical control scheme with either a PID or a sliding mode outer loop controller and a dynamic inversion inner loop controller. A Linear Quadratic Gaussian controller based on a reduced order linear model of the system is used to track lateral commands. The closed loop responses are demonstrated in fully nonlinear simulations with gust disturbances. Finally, we demonstrate a coordinated control of the ailerons to reduce wing curvature excursions from trim values.
