Abstract This study proposes the parametric active aeroelastic control of a folding wing, which is a promising concept of morphing wings, by integrating the parameterized aeroservoelastic model and the receptance-based control strategy. It starts with establishing the parameterized aeroservoelastic model of the folding wing with respect to its folding angle and air speed. The transfer functions between the embedded sensors and the actuators of the folding wing are then efficiently obtained using the parameterized aeroservoelastic model. Finally, control gains for varying folding angle and air speed of the wing are synthesized using the receptance method. The results of numerical analyses show that smooth evolutions of the control gains can be obtained over a wide range of folding angles and air speeds, although the dynamic behavior of the folding wing is sensitive to these parameters. In addition, the active aeroelastic control can effectively suppress aeroelastic vibrations and expand flutter boundaries of the folding wing. The benefit of the parametric active aeroelastic control for the folding wing, i.e., smoothly switching among the control laws without exciting undesirable vibrations is highlighted.

使用感受法的变形机翼参数化主动气动弹性控制

摘要 本研究通过集成参数化气动伺服弹性模型和基于感受器的控制策略，提出了折叠翼的参数化主动气动弹性控制，这是变形机翼的一个很有前景的概念。首先建立折叠机翼折叠角度和风速的参数化气动伺服弹性模型。然后使用参数化的气动伺服弹性模型有效地获得嵌入式传感器和折叠翼致动器之间的传递函数。最后，使用接收方法合成改变机翼折叠角度和空气速度的控制增益。数值分析结果表明，在较宽的折叠角度和空气速度范围内可以获得控制增益的平滑演变，尽管折叠翼的动态行为对这些参数很敏感。此外，主动气动弹性控制可以有效抑制气动弹性振动，扩大折叠翼的颤振边界。折叠翼参数化主动气动弹性控制的好处，即在控制法则之间平滑切换而不会激发不希望的振动。
