Aeroservoelasticity deals with the interactions between structural dynamics, flight controls and unsteady aerodynamics. On a modern aircraft, equipped with active control systems such as flutter suppression, gust load alleviation and other systems, these control systems introduce significant challenges in terms of design, engineering analysis and certification. This technology requires the development of sophisticated software that dictates the control laws of the aircraft. When designing this software, attention has to be given to the aircraft's handling qualities and the effects of the control surfaces on the aircraft's characteristics. While active control systems can improve aerodynamics, loads and flutter, a poorly designed system can make these characteristics worse.

气动伺服弹性研究结构动力学、飞行控制和非定常气动力之间的相互作用。在现代飞机上，装备有主动控制系统，如颤振抑制、阵风载荷减缓和其他系统，这些控制系统在设计、工程分析和认证方面带来了重大挑战。这项技术需要开发复杂的软件来控制飞机的控制律。在设计该软件时，必须注意飞机的操纵品质以及操纵面对飞机特性的影响。虽然主动控制系统可以改善空气动力学、载荷和颤振，但设计不良的系统会使这些特性变差。
