基于射流控制的飞翼布局飞行器大迎角横航向非指令运动抑制

Roll-yaw control of flying wing aircraft at a high angle of attack based on jet control

  • 摘要: 由于复杂的流场结构和涡系间的相互影响,飞翼布局飞行器在大迎角区域易发生横航向非指令运动。为抑制这种运动,基于现有的两种主动射流控制技术,在飞翼布局飞行器上布置了两组射流激励器,并通过风洞测力实验验证了激励器的控制效果。通过大迎角横航向风洞虚拟飞行实验,捕捉了飞翼布局飞行器横航向非指令运动现象,并运用比例–积分–微分(PID)控制和深度强化学习方法对横航向非指令运动进行抑制。风洞实验表明,深度强化学习方法对高耦合、非线性问题的控制效果更好,训练得到的智能体模型能够有效抑制飞翼布局飞行器的横航向非指令运动。

     

    Abstract: The complex flow field structure and the interaction between vortex structures make the flying wing configuration aircraft prone to transverse uncommanded motion at a high angle of attack. To suppress the uncommanded motion, two sets of jet actuators are arranged on the vehicle using two existing active jet control techniques, the control effect of the actuators is verified through wind tunnel force measurement experiments, and the mutual coupling relationship between the two sets of jet actuators is clarified. A virtual flight experiment is conducted in the wind tunnel to capture the uncommanded motion of the flying wing configuration aircraft in the transverse direction, and two methods, PID and deep reinforcement learning, are applied to suppress the uncommanded motion in this kind of highly coupled and nonlinear problem. The wind tunnel experiments show that the deep reinforcement learning method is more effective in controlling the highly coupled and nonlinear problem, and the trained intelligent model can effectively suppress the transverse uncommanded motion of the flying wing configuration aircraft model.
